It uses the `minimatch`\nlibrary to do its matching.\n\n## Attention: node-glob users!\n\nThe API has changed dramatically between 2.x and 3.x. This library is\nnow 100% JavaScript, and the integer flags have been replaced with an\noptions object.\n\nAlso, there's an event emitter class, proper tests, and all the other\nthings you've come to expect from node modules.\n\nAnd best of all, no compilation!\n\n## Usage\n\n```javascript\nvar glob = require(\"glob\")\n\n// options is optional\nglob(\"**/*.js\", options, function (er, files) {\n  // files is an array of filenames.\n  // If the `nonull` option is set, and nothing\n  // was found, then files is [\"**/*.js\"]\n  // er is an error object or null.\n})\n```\n\n## Features\n\nPlease see the [minimatch\ndocumentation](https://github.com/isaacs/minimatch) for more details.\n\nSupports these glob features:\n\n* Brace Expansion\n* Extended glob matching\n* \"Globstar\" `**` matching\n\nSee:\n\n* `man sh`\n* `man bash`\n* `man 3 fnmatch`\n* `man 5 gitignore`\n* [minimatch documentation](https://github.com/isaacs/minimatch)\n\n## glob(pattern, [options], cb)\n\n* `pattern` {String} Pattern to be matched\n* `options` {Object}\n* `cb` {Function}\n  * `err` {Error | null}\n  * `matches` {Array<String>} filenames found matching the pattern\n\nPerform an asynchronous glob search.\n\n## glob.sync(pattern, [options])\n\n* `pattern` {String} Pattern to be matched\n* `options` {Object}\n* return: {Array<String>} filenames found matching the pattern\n\nPerform a synchronous glob search.\n\n## Class: glob.Glob\n\nCreate a Glob object by instanting the `glob.Glob` class.\n\n```javascript\nvar Glob = require(\"glob\").Glob\nvar mg = new Glob(pattern, options, cb)\n```\n\nIt's an EventEmitter, and starts walking the filesystem to find matches\nimmediately.\n\n### new glob.Glob(pattern, [options], [cb])\n\n* `pattern` {String} pattern to search for\n* `options` {Object}\n* `cb` {Function} Called when an error occurs, or matches are found\n  * `err` {Error | null}\n  * `matches` {Array<String>} filenames found matching the pattern\n\nNote that if the `sync` flag is set in the options, then matches will\nbe immediately available on the `g.found` member.\n\n### Properties\n\n* `minimatch` The minimatch object that the glob uses.\n* `options` The options object passed in.\n* `error` The error encountered.  When an error is encountered, the\n  glob object is in an undefined state, and should be discarded.\n* `aborted` Boolean which is set to true when calling `abort()`.  There\n  is no way at this time to continue a glob search after aborting, but\n  you can re-use the statCache to avoid having to duplicate syscalls.\n* `statCache` Collection of all the stat results the glob search\n  performed.\n* `cache` Convenience object.  Each field has the following possible\n  values:\n  * `false` - Path does not exist\n  * `true` - Path exists\n  * `1` - Path exists, and is not a directory\n  * `2` - Path exists, and is a directory\n  * `[file, entries, ...]` - Path exists, is a directory, and the\n    array value is the results of `fs.readdir`\n\n### Events\n\n* `end` When the matching is finished, this is emitted with all the\n  matches found.  If the `nonull` option is set, and no match was found,\n  then the `matches` list contains the original pattern.  The matches\n  are sorted, unless the `nosort` flag is set.\n* `match` Every time a match is found, this is emitted with the matched.\n* `error` Emitted when an unexpected error is encountered, or whenever\n  any fs error occurs if `options.strict` is set.\n* `abort` When `abort()` is called, this event is raised.\n\n### Methods\n\n* `abort` Stop the search.\n\n### Options\n\nAll the options that can be passed to Minimatch can also be passed to\nGlob to change pattern matching behavior.  Also, some have been added,\nor have glob-specific ramifications.\n\nAll options are false by default, unless otherwise noted.\n\nAll options are added to the glob object, as well.\n\n* `cwd` The current working directory in which to search.  Defaults\n  to `process.cwd()`.\n* `root` The place where patterns starting with `/` will be mounted\n  onto.  Defaults to `path.resolve(options.cwd, \"/\")` (`/` on Unix\n  systems, and `C:\\` or some such on Windows.)\n* `dot` Include `.dot` files in normal matches and `globstar` matches.\n  Note that an explicit dot in a portion of the pattern will always\n  match dot files.\n* `nomount` By default, a pattern starting with a forward-slash will be\n  \"mounted\" onto the root setting, so that a valid filesystem path is\n  returned.  Set this flag to disable that behavior.\n* `mark` Add a `/` character to directory matches.  Note that this\n  requires additional stat calls.\n* `nosort` Don't sort the results.\n* `stat` Set to true to stat *all* results.  This reduces performance\n  somewhat, and is completely unnecessary, unless `readdir` is presumed\n  to be an untrustworthy indicator of file existence.  It will cause\n  ELOOP to be triggered one level sooner in the case of cyclical\n  symbolic links.\n* `silent` When an unusual error is encountered\n  when attempting to read a directory, a warning will be printed to\n  stderr.  Set the `silent` option to true to suppress these warnings.\n* `strict` When an unusual error is encountered\n  when attempting to read a directory, the process will just continue on\n  in search of other matches.  Set the `strict` option to raise an error\n  in these cases.\n* `cache` See `cache` property above.  Pass in a previously generated\n  cache object to save some fs calls.\n* `statCache` A cache of results of filesystem information, to prevent\n  unnecessary stat calls.  While it should not normally be necessary to\n  set this, you may pass the statCache from one glob() call to the\n  options object of another, if you know that the filesystem will not\n  change between calls.  (See \"Race Conditions\" below.)\n* `sync` Perform a synchronous glob search.\n* `nounique` In some cases, brace-expanded patterns can result in the\n  same file showing up multiple times in the result set.  By default,\n  this implementation prevents duplicates in the result set.\n  Set this flag to disable that behavior.\n* `nonull` Set to never return an empty set, instead returning a set\n  containing the pattern itself.  This is the default in glob(3).\n* `nocase` Perform a case-insensitive match.  Note that case-insensitive\n  filesystems will sometimes result in glob returning results that are\n  case-insensitively matched anyway, since readdir and stat will not\n  raise an error.\n* `debug` Set to enable debug logging in minimatch and glob.\n* `globDebug` Set to enable debug logging in glob, but not minimatch.\n\n## Comparisons to other fnmatch/glob implementations\n\nWhile strict compliance with the existing standards is a worthwhile\ngoal, some discrepancies exist between node-glob and other\nimplementations, and are intentional.\n\nIf the pattern starts with a `!` character, then it is negated.  Set the\n`nonegate` flag to suppress this behavior, and treat leading `!`\ncharacters normally.  This is perhaps relevant if you wish to start the\npattern with a negative extglob pattern like `!(a|B)`.  Multiple `!`\ncharacters at the start of a pattern will negate the pattern multiple\ntimes.\n\nIf a pattern starts with `#`, then it is treated as a comment, and\nwill not match anything.  Use `\\#` to match a literal `#` at the\nstart of a line, or set the `nocomment` flag to suppress this behavior.\n\nThe double-star character `**` is supported by default, unless the\n`noglobstar` flag is set.  This is supported in the manner of bsdglob\nand bash 4.1, where `**` only has special significance if it is the only\nthing in a path part.  That is, `a/**/b` will match `a/x/y/b`, but\n`a/**b` will not.\n\nIf an escaped pattern has no matches, and the `nonull` flag is set,\nthen glob returns the pattern as-provided, rather than\ninterpreting the character escapes.  For example,\n`glob.match([], \"\\\\*a\\\\?\")` will return `\"\\\\*a\\\\?\"` rather than\n`\"*a?\"`.  This is akin to setting the `nullglob` option in bash, except\nthat it does not resolve escaped pattern characters.\n\nIf brace expansion is not disabled, then it is performed before any\nother interpretation of the glob pattern.  Thus, a pattern like\n`+(a|{b),c)}`, which would not be valid in bash or zsh, is expanded\n**first** into the set of `+(a|b)` and `+(a|c)`, and those patterns are\nchecked for validity.  Since those two are valid, matching proceeds.\n\n## Windows\n\n**Please only use forward-slashes in glob expressions.**\n\nThough windows uses either `/` or `\\` as its path separator, only `/`\ncharacters are used by this glob implementation.  You must use\nforward-slashes **only** in glob expressions.  Back-slashes will always\nbe interpreted as escape characters, not path separators.\n\nResults from absolute patterns such as `/foo/*` are mounted onto the\nroot setting using `path.join`.  On windows, this will by default result\nin `/foo/*` matching `C:\\foo\\bar.txt`.\n\n## Race Conditions\n\nGlob searching, by its very nature, is susceptible to race conditions,\nsince it relies on directory walking and such.\n\nAs a result, it is possible that a file that exists when glob looks for\nit may have been deleted or modified by the time it returns the result.\n\nAs part of its internal implementation, this program caches all stat\nand readdir calls that it makes, in order to cut down on system\noverhead.  However, this also makes it even more susceptible to races,\nespecially if the cache or statCache objects are reused between glob\ncalls.\n\nUsers are thus advised not to use a glob result as a guarantee of\nfilesystem state in the face of rapid changes.  For the vast majority\nof operations, this is never a problem.\n",

+# exit [![Build Status](https://secure.travis-ci.org/cowboy/node-exit.png?branch=master)](http://travis-ci.org/cowboy/node-exit)
+
+A replacement for process.exit that ensures stdio are fully drained before exiting.
+
+To make a long story short, if `process.exit` is called on Windows, script output is often truncated when pipe-redirecting `stdout` or `stderr`. This module attempts to work around this issue by waiting until those streams have been completely drained before actually calling `process.exit`.
+
+See [Node.js issue #3584](https://github.com/joyent/node/issues/3584) for further reference.
+
+Tested in OS X 10.8, Windows 7 on Node.js 0.8.25 and 0.10.18.
+
+Based on some code by [@vladikoff](https://github.com/vladikoff).
+
+## Getting Started
+Install the module with: `npm install exit`
+
+```javascript
+var exit = require('exit');
+
+// These lines should appear in the output, EVEN ON WINDOWS.
+console.log("omg");
+console.error("yay");
+
+// process.exit(5);
+exit(5);
+
+// These lines shouldn't appear in the output.
+console.log("wtf");
+console.error("bro");
+```
+
+## Don't believe me? Try it for yourself.
+
+In Windows, clone the repo and cd to the `test\fixtures` directory. The only difference between [log.js](test/fixtures/log.js) and [log-broken.js](test/fixtures/log-broken.js) is that the former uses `exit` while the latter calls `process.exit` directly.
+
+This test was done using cmd.exe, but you can see the same results using `| grep "std"` in either PowerShell or git-bash.
+
+```
+C:\node-exit\test\fixtures>node log.js 0 10 stdout stderr 2>&1 | find "std"
+stdout 0
+stderr 0
+stdout 1
+stderr 1
+stdout 2
+stderr 2
+stdout 3
+stderr 3
+stdout 4
+stderr 4
+stdout 5
+stderr 5
+stdout 6
+stderr 6
+stdout 7
+stderr 7
+stdout 8
+stderr 8
+stdout 9
+stderr 9
+
+C:\node-exit\test\fixtures>node log-broken.js 0 10 stdout stderr 2>&1 | find "std"
+
+C:\node-exit\test\fixtures>
+```

 # readable-stream
 
-A new class of streams for Node.js
+***Node-core streams for userland***
 
-This module provides the new Stream base classes introduced in Node
-v0.10, for use in Node v0.8.  You can use it to have programs that
-have to work with node v0.8, while being forward-compatible for v0.10
-and beyond.  When you drop support for v0.8, you can remove this
-module, and only use the native streams.
+[![NPM](https://nodei.co/npm/readable-stream.png?downloads=true)](https://nodei.co/npm/readable-stream/)
+[![NPM](https://nodei.co/npm-dl/readable-stream.png)](https://nodei.co/npm/readable-stream/)
 
-This is almost exactly the same codebase as appears in Node v0.10.
-However:
+This package is a mirror of the Streams2 and Streams3 implementations in Node-core.
 
-1. The exported object is actually the Readable class.  Decorating the
-   native `stream` module would be global pollution.
-2. In v0.10, you can safely use `base64` as an argument to
-   `setEncoding` in Readable streams.  However, in v0.8, the
-   StringDecoder class has no `end()` method, which is problematic for
-   Base64.  So, don't use that, because it'll break and be weird.
+If you want to guarantee a stable streams base, regardless of what version of Node you, or the users of your libraries are using, use **readable-stream** *only* and avoid the *"stream"* module in Node-core.
 
-Other than that, the API is the same as `require('stream')` in v0.10,
-so the API docs are reproduced below.
+**readable-stream** comes in two major versions, v1.0.x and v1.1.x. The former tracks the Streams2 implementation in Node 0.10, including bug-fixes and minor improvements as they are added. The latter tracks Streams3 as it develops in Node 0.11; we will likely see a v1.2.x branch for Node 0.12.
 
-----------
+**readable-stream** uses proper patch-level versioning so if you pin to `"~1.0.0"` you’ll get the latest Node 0.10 Streams2 implementation, including any fixes and minor non-breaking improvements. The patch-level versions of 1.0.x and 1.1.x should mirror the patch-level versions of Node-core releases. You should prefer the **1.0.x** releases for now and when you’re ready to start using Streams3, pin to `"~1.1.0"`
 
-    Stability: 2 - Unstable
-
-A stream is an abstract interface implemented by various objects in
-Node.  For example a request to an HTTP server is a stream, as is
-stdout. Streams are readable, writable, or both. All streams are
-instances of [EventEmitter][]
-
-You can load the Stream base classes by doing `require('stream')`.
-There are base classes provided for Readable streams, Writable
-streams, Duplex streams, and Transform streams.
-
-## Compatibility
-
-In earlier versions of Node, the Readable stream interface was
-simpler, but also less powerful and less useful.
-
-* Rather than waiting for you to call the `read()` method, `'data'`
-  events would start emitting immediately.  If you needed to do some
-  I/O to decide how to handle data, then you had to store the chunks
-  in some kind of buffer so that they would not be lost.
-* The `pause()` method was advisory, rather than guaranteed.  This
-  meant that you still had to be prepared to receive `'data'` events
-  even when the stream was in a paused state.
-
-In Node v0.10, the Readable class described below was added.  For
-backwards compatibility with older Node programs, Readable streams
-switch into "old mode" when a `'data'` event handler is added, or when
-the `pause()` or `resume()` methods are called.  The effect is that,
-even if you are not using the new `read()` method and `'readable'`
-event, you no longer have to worry about losing `'data'` chunks.
-
-Most programs will continue to function normally.  However, this
-introduces an edge case in the following conditions:
-
-* No `'data'` event handler is added.
-* The `pause()` and `resume()` methods are never called.
-
-For example, consider the following code:
-
-```javascript
-// WARNING!  BROKEN!
-net.createServer(function(socket) {
-
-  // we add an 'end' method, but never consume the data
-  socket.on('end', function() {
-    // It will never get here.
-    socket.end('I got your message (but didnt read it)\n');
-  });
-
-}).listen(1337);
-```
-
-In versions of node prior to v0.10, the incoming message data would be
-simply discarded.  However, in Node v0.10 and beyond, the socket will
-remain paused forever.
-
-The workaround in this situation is to call the `resume()` method to
-trigger "old mode" behavior:
-
-```javascript
-// Workaround
-net.createServer(function(socket) {
-
-  socket.on('end', function() {
-    socket.end('I got your message (but didnt read it)\n');
-  });
-
-  // start the flow of data, discarding it.
-  socket.resume();
-
-}).listen(1337);
-```
-
-In addition to new Readable streams switching into old-mode, pre-v0.10
-style streams can be wrapped in a Readable class using the `wrap()`
-method.
-
-## Class: stream.Readable
-
-<!--type=class-->
-
-A `Readable Stream` has the following methods, members, and events.
-
-Note that `stream.Readable` is an abstract class designed to be
-extended with an underlying implementation of the `_read(size)`
-method. (See below.)
-
-### new stream.Readable([options])
-
-* `options` {Object}
-  * `highWaterMark` {Number} The maximum number of bytes to store in
-    the internal buffer before ceasing to read from the underlying
-    resource.  Default=16kb
-  * `encoding` {String} If specified, then buffers will be decoded to
-    strings using the specified encoding.  Default=null
-  * `objectMode` {Boolean} Whether this stream should behave
-    as a stream of objects. Meaning that stream.read(n) returns
-    a single value instead of a Buffer of size n
-
-In classes that extend the Readable class, make sure to call the
-constructor so that the buffering settings can be properly
-initialized.
-
-### readable.\_read(size)
-
-* `size` {Number} Number of bytes to read asynchronously
-
-Note: **This function should NOT be called directly.**  It should be
-implemented by child classes, and called by the internal Readable
-class methods only.
-
-All Readable stream implementations must provide a `_read` method
-to fetch data from the underlying resource.
-
-This method is prefixed with an underscore because it is internal to
-the class that defines it, and should not be called directly by user
-programs.  However, you **are** expected to override this method in
-your own extension classes.
-
-When data is available, put it into the read queue by calling
-`readable.push(chunk)`.  If `push` returns false, then you should stop
-reading.  When `_read` is called again, you should start pushing more
-data.
-
-The `size` argument is advisory.  Implementations where a "read" is a
-single call that returns data can use this to know how much data to
-fetch.  Implementations where that is not relevant, such as TCP or
-TLS, may ignore this argument, and simply provide data whenever it
-becomes available.  There is no need, for example to "wait" until
-`size` bytes are available before calling `stream.push(chunk)`.
-
-### readable.push(chunk)
-
-* `chunk` {Buffer | null | String} Chunk of data to push into the read queue
-* return {Boolean} Whether or not more pushes should be performed
-
-Note: **This function should be called by Readable implementors, NOT
-by consumers of Readable subclasses.**  The `_read()` function will not
-be called again until at least one `push(chunk)` call is made.  If no
-data is available, then you MAY call `push('')` (an empty string) to
-allow a future `_read` call, without adding any data to the queue.
-
-The `Readable` class works by putting data into a read queue to be
-pulled out later by calling the `read()` method when the `'readable'`
-event fires.
-
-The `push()` method will explicitly insert some data into the read
-queue.  If it is called with `null` then it will signal the end of the
-data.
-
-In some cases, you may be wrapping a lower-level source which has some
-sort of pause/resume mechanism, and a data callback.  In those cases,
-you could wrap the low-level source object by doing something like
-this:
-
-```javascript
-// source is an object with readStop() and readStart() methods,
-// and an `ondata` member that gets called when it has data, and
-// an `onend` member that gets called when the data is over.
-
-var stream = new Readable();
-
-source.ondata = function(chunk) {
-  // if push() returns false, then we need to stop reading from source
-  if (!stream.push(chunk))
-    source.readStop();
-};
-
-source.onend = function() {
-  stream.push(null);
-};
-
-// _read will be called when the stream wants to pull more data in
-// the advisory size argument is ignored in this case.
-stream._read = function(n) {
-  source.readStart();
-};
-```
-
-### readable.unshift(chunk)
-
-* `chunk` {Buffer | null | String} Chunk of data to unshift onto the read queue
-* return {Boolean} Whether or not more pushes should be performed
-
-This is the corollary of `readable.push(chunk)`.  Rather than putting
-the data at the *end* of the read queue, it puts it at the *front* of
-the read queue.
-
-This is useful in certain use-cases where a stream is being consumed
-by a parser, which needs to "un-consume" some data that it has
-optimistically pulled out of the source.
-
-```javascript
-// A parser for a simple data protocol.
-// The "header" is a JSON object, followed by 2 \n characters, and
-// then a message body.
-//
-// Note: This can be done more simply as a Transform stream.  See below.
-
-function SimpleProtocol(source, options) {
-  if (!(this instanceof SimpleProtocol))
-    return new SimpleProtocol(options);
-
-  Readable.call(this, options);
-  this._inBody = false;
-  this._sawFirstCr = false;
-
-  // source is a readable stream, such as a socket or file
-  this._source = source;
-
-  var self = this;
-  source.on('end', function() {
-    self.push(null);
-  });
-
-  // give it a kick whenever the source is readable
-  // read(0) will not consume any bytes
-  source.on('readable', function() {
-    self.read(0);
-  });
-
-  this._rawHeader = [];
-  this.header = null;
-}
-
-SimpleProtocol.prototype = Object.create(
-  Readable.prototype, { constructor: { value: SimpleProtocol }});
-
-SimpleProtocol.prototype._read = function(n) {
-  if (!this._inBody) {
-    var chunk = this._source.read();
-
-    // if the source doesn't have data, we don't have data yet.
-    if (chunk === null)
-      return this.push('');
-
-    // check if the chunk has a \n\n
-    var split = -1;
-    for (var i = 0; i < chunk.length; i++) {
-      if (chunk[i] === 10) { // '\n'
-        if (this._sawFirstCr) {
-          split = i;
-          break;
-        } else {
-          this._sawFirstCr = true;
-        }
-      } else {
-        this._sawFirstCr = false;
-      }
-    }
-
-    if (split === -1) {
-      // still waiting for the \n\n
-      // stash the chunk, and try again.
-      this._rawHeader.push(chunk);
-      this.push('');
-    } else {
-      this._inBody = true;
-      var h = chunk.slice(0, split);
-      this._rawHeader.push(h);
-      var header = Buffer.concat(this._rawHeader).toString();
-      try {
-        this.header = JSON.parse(header);
-      } catch (er) {
-        this.emit('error', new Error('invalid simple protocol data'));
-        return;
-      }
-      // now, because we got some extra data, unshift the rest
-      // back into the read queue so that our consumer will see it.
-      var b = chunk.slice(split);
-      this.unshift(b);
-
-      // and let them know that we are done parsing the header.
-      this.emit('header', this.header);
-    }
-  } else {
-    // from there on, just provide the data to our consumer.
-    // careful not to push(null), since that would indicate EOF.
-    var chunk = this._source.read();
-    if (chunk) this.push(chunk);
-  }
-};
-
-// Usage:
-var parser = new SimpleProtocol(source);
-// Now parser is a readable stream that will emit 'header'
-// with the parsed header data.
-```
-
-### readable.wrap(stream)
-
-* `stream` {Stream} An "old style" readable stream
-
-If you are using an older Node library that emits `'data'` events and
-has a `pause()` method that is advisory only, then you can use the
-`wrap()` method to create a Readable stream that uses the old stream
-as its data source.
-
-For example:
-
-```javascript
-var OldReader = require('./old-api-module.js').OldReader;
-var oreader = new OldReader;
-var Readable = require('stream').Readable;
-var myReader = new Readable().wrap(oreader);
-
-myReader.on('readable', function() {
-  myReader.read(); // etc.
-});
-```
-
-### Event: 'readable'
-
-When there is data ready to be consumed, this event will fire.
-
-When this event emits, call the `read()` method to consume the data.
-
-### Event: 'end'
-
-Emitted when the stream has received an EOF (FIN in TCP terminology).
-Indicates that no more `'data'` events will happen. If the stream is
-also writable, it may be possible to continue writing.
-
-### Event: 'data'
-
-The `'data'` event emits either a `Buffer` (by default) or a string if
-`setEncoding()` was used.
-
-Note that adding a `'data'` event listener will switch the Readable
-stream into "old mode", where data is emitted as soon as it is
-available, rather than waiting for you to call `read()` to consume it.
-
-### Event: 'error'
-
-Emitted if there was an error receiving data.
-
-### Event: 'close'
-
-Emitted when the underlying resource (for example, the backing file
-descriptor) has been closed. Not all streams will emit this.
-
-### readable.setEncoding(encoding)
-
-Makes the `'data'` event emit a string instead of a `Buffer`. `encoding`
-can be `'utf8'`, `'utf16le'` (`'ucs2'`), `'ascii'`, or `'hex'`.
-
-The encoding can also be set by specifying an `encoding` field to the
-constructor.
-
-### readable.read([size])
-
-* `size` {Number | null} Optional number of bytes to read.
-* Return: {Buffer | String | null}
-
-Note: **This function SHOULD be called by Readable stream users.**
-
-Call this method to consume data once the `'readable'` event is
-emitted.
-
-The `size` argument will set a minimum number of bytes that you are
-interested in.  If not set, then the entire content of the internal
-buffer is returned.
-
-If there is no data to consume, or if there are fewer bytes in the
-internal buffer than the `size` argument, then `null` is returned, and
-a future `'readable'` event will be emitted when more is available.
-
-Calling `stream.read(0)` will always return `null`, and will trigger a
-refresh of the internal buffer, but otherwise be a no-op.
-
-### readable.pipe(destination, [options])
-
-* `destination` {Writable Stream}
-* `options` {Object} Optional
-  * `end` {Boolean} Default=true
-
-Connects this readable stream to `destination` WriteStream. Incoming
-data on this stream gets written to `destination`.  Properly manages
-back-pressure so that a slow destination will not be overwhelmed by a
-fast readable stream.
-
-This function returns the `destination` stream.
-
-For example, emulating the Unix `cat` command:
-
-    process.stdin.pipe(process.stdout);
-
-By default `end()` is called on the destination when the source stream
-emits `end`, so that `destination` is no longer writable. Pass `{ end:
-false }` as `options` to keep the destination stream open.
-
-This keeps `writer` open so that "Goodbye" can be written at the
-end.
-
-    reader.pipe(writer, { end: false });
-    reader.on("end", function() {
-      writer.end("Goodbye\n");
-    });
-
-Note that `process.stderr` and `process.stdout` are never closed until
-the process exits, regardless of the specified options.
-
-### readable.unpipe([destination])
-
-* `destination` {Writable Stream} Optional
-
-Undo a previously established `pipe()`.  If no destination is
-provided, then all previously established pipes are removed.
-
-### readable.pause()
-
-Switches the readable stream into "old mode", where data is emitted
-using a `'data'` event rather than being buffered for consumption via
-the `read()` method.
-
-Ceases the flow of data.  No `'data'` events are emitted while the
-stream is in a paused state.
-
-### readable.resume()
-
-Switches the readable stream into "old mode", where data is emitted
-using a `'data'` event rather than being buffered for consumption via
-the `read()` method.
-
-Resumes the incoming `'data'` events after a `pause()`.
-
-
-## Class: stream.Writable
-
-<!--type=class-->
-
-A `Writable` Stream has the following methods, members, and events.
-
-Note that `stream.Writable` is an abstract class designed to be
-extended with an underlying implementation of the
-`_write(chunk, encoding, cb)` method. (See below.)
-
-### new stream.Writable([options])
-
-* `options` {Object}
-  * `highWaterMark` {Number} Buffer level when `write()` starts
-    returning false. Default=16kb
-  * `decodeStrings` {Boolean} Whether or not to decode strings into
-    Buffers before passing them to `_write()`.  Default=true
-
-In classes that extend the Writable class, make sure to call the
-constructor so that the buffering settings can be properly
-initialized.
-
-### writable.\_write(chunk, encoding, callback)
-
-* `chunk` {Buffer | String} The chunk to be written.  Will always
-  be a buffer unless the `decodeStrings` option was set to `false`.
-* `encoding` {String} If the chunk is a string, then this is the
-  encoding type.  Ignore chunk is a buffer.  Note that chunk will
-  **always** be a buffer unless the `decodeStrings` option is
-  explicitly set to `false`.
-* `callback` {Function} Call this function (optionally with an error
-  argument) when you are done processing the supplied chunk.
-
-All Writable stream implementations must provide a `_write` method to
-send data to the underlying resource.
-
-Note: **This function MUST NOT be called directly.**  It should be
-implemented by child classes, and called by the internal Writable
-class methods only.
-
-Call the callback using the standard `callback(error)` pattern to
-signal that the write completed successfully or with an error.
-
-If the `decodeStrings` flag is set in the constructor options, then
-`chunk` may be a string rather than a Buffer, and `encoding` will
-indicate the sort of string that it is.  This is to support
-implementations that have an optimized handling for certain string
-data encodings.  If you do not explicitly set the `decodeStrings`
-option to `false`, then you can safely ignore the `encoding` argument,
-and assume that `chunk` will always be a Buffer.
-
-This method is prefixed with an underscore because it is internal to
-the class that defines it, and should not be called directly by user
-programs.  However, you **are** expected to override this method in
-your own extension classes.
-
-
-### writable.write(chunk, [encoding], [callback])
-
-* `chunk` {Buffer | String} Data to be written
-* `encoding` {String} Optional.  If `chunk` is a string, then encoding
-  defaults to `'utf8'`
-* `callback` {Function} Optional.  Called when this chunk is
-  successfully written.
-* Returns {Boolean}
-
-Writes `chunk` to the stream.  Returns `true` if the data has been
-flushed to the underlying resource.  Returns `false` to indicate that
-the buffer is full, and the data will be sent out in the future. The
-`'drain'` event will indicate when the buffer is empty again.
-
-The specifics of when `write()` will return false, is determined by
-the `highWaterMark` option provided to the constructor.
-
-### writable.end([chunk], [encoding], [callback])
-
-* `chunk` {Buffer | String} Optional final data to be written
-* `encoding` {String} Optional.  If `chunk` is a string, then encoding
-  defaults to `'utf8'`
-* `callback` {Function} Optional.  Called when the final chunk is
-  successfully written.
-
-Call this method to signal the end of the data being written to the
-stream.
-
-### Event: 'drain'
-
-Emitted when the stream's write queue empties and it's safe to write
-without buffering again. Listen for it when `stream.write()` returns
-`false`.
-
-### Event: 'close'
-
-Emitted when the underlying resource (for example, the backing file
-descriptor) has been closed. Not all streams will emit this.
-
-### Event: 'finish'
-
-When `end()` is called and there are no more chunks to write, this
-event is emitted.
-
-### Event: 'pipe'
-
-* `source` {Readable Stream}
-
-Emitted when the stream is passed to a readable stream's pipe method.
-
-### Event 'unpipe'
-
-* `source` {Readable Stream}
-
-Emitted when a previously established `pipe()` is removed using the
-source Readable stream's `unpipe()` method.
-
-## Class: stream.Duplex
-
-<!--type=class-->
-
-A "duplex" stream is one that is both Readable and Writable, such as a
-TCP socket connection.
-
-Note that `stream.Duplex` is an abstract class designed to be
-extended with an underlying implementation of the `_read(size)`
-and `_write(chunk, encoding, callback)` methods as you would with a Readable or
-Writable stream class.
-
-Since JavaScript doesn't have multiple prototypal inheritance, this
-class prototypally inherits from Readable, and then parasitically from
-Writable.  It is thus up to the user to implement both the lowlevel
-`_read(n)` method as well as the lowlevel `_write(chunk, encoding, cb)` method
-on extension duplex classes.
-
-### new stream.Duplex(options)
-
-* `options` {Object} Passed to both Writable and Readable
-  constructors. Also has the following fields:
-  * `allowHalfOpen` {Boolean} Default=true.  If set to `false`, then
-    the stream will automatically end the readable side when the
-    writable side ends and vice versa.
-
-In classes that extend the Duplex class, make sure to call the
-constructor so that the buffering settings can be properly
-initialized.
-
-## Class: stream.Transform
-
-A "transform" stream is a duplex stream where the output is causally
-connected in some way to the input, such as a zlib stream or a crypto
-stream.
-
-There is no requirement that the output be the same size as the input,
-the same number of chunks, or arrive at the same time.  For example, a
-Hash stream will only ever have a single chunk of output which is
-provided when the input is ended.  A zlib stream will either produce
-much smaller or much larger than its input.
-
-Rather than implement the `_read()` and `_write()` methods, Transform
-classes must implement the `_transform()` method, and may optionally
-also implement the `_flush()` method.  (See below.)
-
-### new stream.Transform([options])
-
-* `options` {Object} Passed to both Writable and Readable
-  constructors.
-
-In classes that extend the Transform class, make sure to call the
-constructor so that the buffering settings can be properly
-initialized.
-
-### transform.\_transform(chunk, encoding, callback)
-
-* `chunk` {Buffer | String} The chunk to be transformed.  Will always
-  be a buffer unless the `decodeStrings` option was set to `false`.
-* `encoding` {String} If the chunk is a string, then this is the
-  encoding type.  (Ignore if `decodeStrings` chunk is a buffer.)
-* `callback` {Function} Call this function (optionally with an error
-  argument) when you are done processing the supplied chunk.
-
-Note: **This function MUST NOT be called directly.**  It should be
-implemented by child classes, and called by the internal Transform
-class methods only.
-
-All Transform stream implementations must provide a `_transform`
-method to accept input and produce output.
-
-`_transform` should do whatever has to be done in this specific
-Transform class, to handle the bytes being written, and pass them off
-to the readable portion of the interface.  Do asynchronous I/O,
-process things, and so on.
-
-Call `transform.push(outputChunk)` 0 or more times to generate output
-from this input chunk, depending on how much data you want to output
-as a result of this chunk.
-
-Call the callback function only when the current chunk is completely
-consumed.  Note that there may or may not be output as a result of any
-particular input chunk.
-
-This method is prefixed with an underscore because it is internal to
-the class that defines it, and should not be called directly by user
-programs.  However, you **are** expected to override this method in
-your own extension classes.
-
-### transform.\_flush(callback)
-
-* `callback` {Function} Call this function (optionally with an error
-  argument) when you are done flushing any remaining data.
-
-Note: **This function MUST NOT be called directly.**  It MAY be implemented
-by child classes, and if so, will be called by the internal Transform
-class methods only.
-
-In some cases, your transform operation may need to emit a bit more
-data at the end of the stream.  For example, a `Zlib` compression
-stream will store up some internal state so that it can optimally
-compress the output.  At the end, however, it needs to do the best it
-can with what is left, so that the data will be complete.
-
-In those cases, you can implement a `_flush` method, which will be
-called at the very end, after all the written data is consumed, but
-before emitting `end` to signal the end of the readable side.  Just
-like with `_transform`, call `transform.push(chunk)` zero or more
-times, as appropriate, and call `callback` when the flush operation is
-complete.
-
-This method is prefixed with an underscore because it is internal to
-the class that defines it, and should not be called directly by user
-programs.  However, you **are** expected to override this method in
-your own extension classes.
-
-### Example: `SimpleProtocol` parser
-
-The example above of a simple protocol parser can be implemented much
-more simply by using the higher level `Transform` stream class.
-
-In this example, rather than providing the input as an argument, it
-would be piped into the parser, which is a more idiomatic Node stream
-approach.
-
-```javascript
-function SimpleProtocol(options) {
-  if (!(this instanceof SimpleProtocol))
-    return new SimpleProtocol(options);
-
-  Transform.call(this, options);
-  this._inBody = false;
-  this._sawFirstCr = false;
-  this._rawHeader = [];
-  this.header = null;
-}
-
-SimpleProtocol.prototype = Object.create(
-  Transform.prototype, { constructor: { value: SimpleProtocol }});
-
-SimpleProtocol.prototype._transform = function(chunk, encoding, done) {
-  if (!this._inBody) {
-    // check if the chunk has a \n\n
-    var split = -1;
-    for (var i = 0; i < chunk.length; i++) {
-      if (chunk[i] === 10) { // '\n'
-        if (this._sawFirstCr) {
-          split = i;
-          break;
-        } else {
-          this._sawFirstCr = true;
-        }
-      } else {
-        this._sawFirstCr = false;
-      }
-    }
-
-    if (split === -1) {
-      // still waiting for the \n\n
-      // stash the chunk, and try again.
-      this._rawHeader.push(chunk);
-    } else {
-      this._inBody = true;
-      var h = chunk.slice(0, split);
-      this._rawHeader.push(h);
-      var header = Buffer.concat(this._rawHeader).toString();
-      try {
-        this.header = JSON.parse(header);
-      } catch (er) {
-        this.emit('error', new Error('invalid simple protocol data'));
-        return;
-      }
-      // and let them know that we are done parsing the header.
-      this.emit('header', this.header);
-
-      // now, because we got some extra data, emit this first.
-      this.push(b);
-    }
-  } else {
-    // from there on, just provide the data to our consumer as-is.
-    this.push(b);
-  }
-  done();
-};
-
-var parser = new SimpleProtocol();
-source.pipe(parser)
-
-// Now parser is a readable stream that will emit 'header'
-// with the parsed header data.
-```
-
-
-## Class: stream.PassThrough
-
-This is a trivial implementation of a `Transform` stream that simply
-passes the input bytes across to the output.  Its purpose is mainly
-for examples and testing, but there are occasionally use cases where
-it can come in handy.

You can use it to have programs that\nhave to work with node v0.8, while being forward-compatible for v0.10\nand beyond.  When you drop support for v0.8, you can remove this\nmodule, and only use the native streams.\n\nThis is almost exactly the same codebase as appears in Node v0.10.\nHowever:\n\n1. The exported object is actually the Readable class.  Decorating the\n   native `stream` module would be global pollution.\n2. In v0.10, you can safely use `base64` as an argument to\n   `setEncoding` in Readable streams.  However, in v0.8, the\n   StringDecoder class has no `end()` method, which is problematic for\n   Base64.  So, don't use that, because it'll break and be weird.\n\nOther than that, the API is the same as `require('stream')` in v0.10,\nso the API docs are reproduced below.\n\n----------\n\n    Stability: 2 - Unstable\n\nA stream is an abstract interface implemented by various objects in\nNode.  For example a request to an HTTP server is a stream, as is\nstdout. Streams are readable, writable, or both. All streams are\ninstances of [EventEmitter][]\n\nYou can load the Stream base classes by doing `require('stream')`.\nThere are base classes provided for Readable streams, Writable\nstreams, Duplex streams, and Transform streams.\n\n## Compatibility\n\nIn earlier versions of Node, the Readable stream interface was\nsimpler, but also less powerful and less useful.\n\n* Rather than waiting for you to call the `read()` method, `'data'`\n  events would start emitting immediately.  If you needed to do some\n  I/O to decide how to handle data, then you had to store the chunks\n  in some kind of buffer so that they would not be lost.\n* The `pause()` method was advisory, rather than guaranteed.  This\n  meant that you still had to be prepared to receive `'data'` events\n  even when the stream was in a paused state.\n\nIn Node v0.10, the Readable class described below was added.  For\nbackwards compatibility with older Node programs, Readable streams\nswitch into \"old mode\" when a `'data'` event handler is added, or when\nthe `pause()` or `resume()` methods are called.  The effect is that,\neven if you are not using the new `read()` method and `'readable'`\nevent, you no longer have to worry about losing `'data'` chunks.\n\nMost programs will continue to function normally.  However, this\nintroduces an edge case in the following conditions:\n\n* No `'data'` event handler is added.\n* The `pause()` and `resume()` methods are never called.\n\nFor example, consider the following code:\n\n```javascript\n// WARNING!  BROKEN!\nnet.createServer(function(socket) {\n\n  // we add an 'end' method, but never consume the data\n  socket.on('end', function() {\n    // It will never get here.\n    socket.end('I got your message (but didnt read it)\\n');\n  });\n\n}).listen(1337);\n```\n\nIn versions of node prior to v0.10, the incoming message data would be\nsimply discarded.  However, in Node v0.10 and beyond, the socket will\nremain paused forever.\n\nThe workaround in this situation is to call the `resume()` method to\ntrigger \"old mode\" behavior:\n\n```javascript\n// Workaround\nnet.createServer(function(socket) {\n\n  socket.on('end', function() {\n    socket.end('I got your message (but didnt read it)\\n');\n  });\n\n  // start the flow of data, discarding it.\n  socket.resume();\n\n}).listen(1337);\n```\n\nIn addition to new Readable streams switching into old-mode, pre-v0.10\nstyle streams can be wrapped in a Readable class using the `wrap()`\nmethod.\n\n## Class: stream.Readable\n\n<!--type=class-->\n\nA `Readable Stream` has the following methods, members, and events.\n\nNote that `stream.Readable` is an abstract class designed to be\nextended with an underlying implementation of the `_read(size)`\nmethod. (See below.)\n\n### new stream.Readable([options])\n\n* `options` {Object}\n  * `highWaterMark` {Number} The maximum number of bytes to store in\n    the internal buffer before ceasing to read from the underlying\n    resource.  Default=16kb\n  * `encoding` {String} If specified, then buffers will be decoded to\n    strings using the specified encoding.  Default=null\n  * `objectMode` {Boolean} Whether this stream should behave\n    as a stream of objects. Meaning that stream.read(n) returns\n    a single value instead of a Buffer of size n\n\nIn classes that extend the Readable class, make sure to call the\nconstructor so that the buffering settings can be properly\ninitialized.\n\n### readable.\\_read(size)\n\n* `size` {Number} Number of bytes to read asynchronously\n\nNote: **This function should NOT be called directly.**  It should be\nimplemented by child classes, and called by the internal Readable\nclass methods only.\n\nAll Readable stream implementations must provide a `_read` method\nto fetch data from the underlying resource.\n\nThis method is prefixed with an underscore because it is internal to\nthe class that defines it, and should not be called directly by user\nprograms.  However, you **are** expected to override this method in\nyour own extension classes.\n\nWhen data is available, put it into the read queue by calling\n`readable.push(chunk)`.  If `push` returns false, then you should stop\nreading.  When `_read` is called again, you should start pushing more\ndata.\n\nThe `size` argument is advisory.  Implementations where a \"read\" is a\nsingle call that returns data can use this to know how much data to\nfetch.  Implementations where that is not relevant, such as TCP or\nTLS, may ignore this argument, and simply provide data whenever it\nbecomes available.  There is no need, for example to \"wait\" until\n`size` bytes are available before calling `stream.push(chunk)`.\n\n### readable.push(chunk)\n\n* `chunk` {Buffer | null | String} Chunk of data to push into the read queue\n* return {Boolean} Whether or not more pushes should be performed\n\nNote: **This function should be called by Readable implementors, NOT\nby consumers of Readable subclasses.**  The `_read()` function will not\nbe called again until at least one `push(chunk)` call is made.  If no\ndata is available, then you MAY call `push('')` (an empty string) to\nallow a future `_read` call, without adding any data to the queue.\n\nThe `Readable` class works by putting data into a read queue to be\npulled out later by calling the `read()` method when the `'readable'`\nevent fires.\n\nThe `push()` method will explicitly insert some data into the read\nqueue.  If it is called with `null` then it will signal the end of the\ndata.\n\nIn some cases, you may be wrapping a lower-level source which has some\nsort of pause/resume mechanism, and a data callback.  In those cases,\nyou could wrap the low-level source object by doing something like\nthis:\n\n```javascript\n// source is an object with readStop() and readStart() methods,\n// and an `ondata` member that gets called when it has data, and\n// an `onend` member that gets called when the data is over.\n\nvar stream = new Readable();\n\nsource.ondata = function(chunk) {\n  // if push() returns false, then we need to stop reading from source\n  if (!stream.push(chunk))\n    source.readStop();\n};\n\nsource.onend = function() {\n  stream.push(null);\n};\n\n// _read will be called when the stream wants to pull more data in\n// the advisory size argument is ignored in this case.\nstream._read = function(n) {\n  source.readStart();\n};\n```\n\n### readable.unshift(chunk)\n\n* `chunk` {Buffer | null | String} Chunk of data to unshift onto the read queue\n* return {Boolean} Whether or not more pushes should be performed\n\nThis is the corollary of `readable.push(chunk)`.  Rather than putting\nthe data at the *end* of the read queue, it puts it at the *front* of\nthe read queue.\n\nThis is useful in certain use-cases where a stream is being consumed\nby a parser, which needs to \"un-consume\" some data that it has\noptimistically pulled out of the source.\n\n```javascript\n// A parser for a simple data protocol.\n// The \"header\" is a JSON object, followed by 2 \\n characters, and\n// then a message body.\n//\n// Note: This can be done more simply as a Transform stream.  See below.\n\nfunction SimpleProtocol(source, options) {\n  if (!(this instanceof SimpleProtocol))\n    return new SimpleProtocol(options);\n\n  Readable.call(this, options);\n  this._inBody = false;\n  this._sawFirstCr = false;\n\n  // source is a readable stream, such as a socket or file\n  this._source = source;\n\n  var self = this;\n  source.on('end', function() {\n    self.push(null);\n  });\n\n  // give it a kick whenever the source is readable\n  // read(0) will not consume any bytes\n  source.on('readable', function() {\n    self.read(0);\n  });\n\n  this._rawHeader = [];\n  this.header = null;\n}\n\nSimpleProtocol.prototype = Object.create(\n  Readable.prototype, { constructor: { value: SimpleProtocol }});\n\nSimpleProtocol.prototype._read = function(n) {\n  if (!this._inBody) {\n    var chunk = this._source.read();\n\n    // if the source doesn't have data, we don't have data yet.\n    if (chunk === null)\n      return this.push('');\n\n    // check if the chunk has a \\n\\n\n    var split = -1;\n    for (var i = 0; i < chunk.length; i++) {\n      if (chunk[i] === 10) { // '\\n'\n        if (this._sawFirstCr) {\n          split = i;\n          break;\n        } else {\n          this._sawFirstCr = true;\n        }\n      } else {\n        this._sawFirstCr = false;\n      }\n    }\n\n    if (split === -1) {\n      // still waiting for the \\n\\n\n      // stash the chunk, and try again.\n      this._rawHeader.push(chunk);\n      this.push('');\n    } else {\n      this._inBody = true;\n      var h = chunk.slice(0, split);\n      this._rawHeader.push(h);\n      var header = Buffer.concat(this._rawHeader).toString();\n      try {\n        this.header = JSON.parse(header);\n      } catch (er) {\n        this.emit('error', new Error('invalid simple protocol data'));\n        return;\n      }\n      // now, because we got some extra data, unshift the rest\n      // back into the read queue so that our consumer will see it.\n      var b = chunk.slice(split);\n      this.unshift(b);\n\n      // and let them know that we are done parsing the header.\n      this.emit('header', this.header);\n    }\n  } else {\n    // from there on, just provide the data to our consumer.\n    // careful not to push(null), since that would indicate EOF.\n    var chunk = this._source.read();\n    if (chunk) this.push(chunk);\n  }\n};\n\n// Usage:\nvar parser = new SimpleProtocol(source);\n// Now parser is a readable stream that will emit 'header'\n// with the parsed header data.\n```\n\n### readable.wrap(stream)\n\n* `stream` {Stream} An \"old style\" readable stream\n\nIf you are using an older Node library that emits `'data'` events and\nhas a `pause()` method that is advisory only, then you can use the\n`wrap()` method to create a Readable stream that uses the old stream\nas its data source.\n\nFor example:\n\n```javascript\nvar OldReader = require('./old-api-module.js').OldReader;\nvar oreader = new OldReader;\nvar Readable = require('stream').Readable;\nvar myReader = new Readable().wrap(oreader);\n\nmyReader.on('readable', function() {\n  myReader.read(); // etc.\n});\n```\n\n### Event: 'readable'\n\nWhen there is data ready to be consumed, this event will fire.\n\nWhen this event emits, call the `read()` method to consume the data.\n\n### Event: 'end'\n\nEmitted when the stream has received an EOF (FIN in TCP terminology).\nIndicates that no more `'data'` events will happen. If the stream is\nalso writable, it may be possible to continue writing.\n\n### Event: 'data'\n\nThe `'data'` event emits either a `Buffer` (by default) or a string if\n`setEncoding()` was used.\n\nNote that adding a `'data'` event listener will switch the Readable\nstream into \"old mode\", where data is emitted as soon as it is\navailable, rather than waiting for you to call `read()` to consume it.\n\n### Event: 'error'\n\nEmitted if there was an error receiving data.\n\n### Event: 'close'\n\nEmitted when the underlying resource (for example, the backing file\ndescriptor) has been closed. Not all streams will emit this.\n\n### readable.setEncoding(encoding)\n\nMakes the `'data'` event emit a string instead of a `Buffer`. `encoding`\ncan be `'utf8'`, `'utf16le'` (`'ucs2'`), `'ascii'`, or `'hex'`.\n\nThe encoding can also be set by specifying an `encoding` field to the\nconstructor.\n\n### readable.read([size])\n\n* `size` {Number | null} Optional number of bytes to read.\n* Return: {Buffer | String | null}\n\nNote: **This function SHOULD be called by Readable stream users.**\n\nCall this method to consume data once the `'readable'` event is\nemitted.\n\nThe `size` argument will set a minimum number of bytes that you are\ninterested in.  If not set, then the entire content of the internal\nbuffer is returned.\n\nIf there is no data to consume, or if there are fewer bytes in the\ninternal buffer than the `size` argument, then `null` is returned, and\na future `'readable'` event will be emitted when more is available.\n\nCalling `stream.read(0)` will always return `null`, and will trigger a\nrefresh of the internal buffer, but otherwise be a no-op.\n\n### readable.pipe(destination, [options])\n\n* `destination` {Writable Stream}\n* `options` {Object} Optional\n  * `end` {Boolean} Default=true\n\nConnects this readable stream to `destination` WriteStream. Incoming\ndata on this stream gets written to `destination`.  Properly manages\nback-pressure so that a slow destination will not be overwhelmed by a\nfast readable stream.\n\nThis function returns the `destination` stream.\n\nFor example, emulating the Unix `cat` command:\n\n    process.stdin.pipe(process.stdout);\n\nBy default `end()` is called on the destination when the source stream\nemits `end`, so that `destination` is no longer writable. Pass `{ end:\nfalse }` as `options` to keep the destination stream open.\n\nThis keeps `writer` open so that \"Goodbye\" can be written at the\nend.\n\n    reader.pipe(writer, { end: false });\n    reader.on(\"end\", function() {\n      writer.end(\"Goodbye\\n\");\n    });\n\nNote that `process.stderr` and `process.stdout` are never closed until\nthe process exits, regardless of the specified options.\n\n### readable.unpipe([destination])\n\n* `destination` {Writable Stream} Optional\n\nUndo a previously established `pipe()`.  If no destination is\nprovided, then all previously established pipes are removed.\n\n### readable.pause()\n\nSwitches the readable stream into \"old mode\", where data is emitted\nusing a `'data'` event rather than being buffered for consumption via\nthe `read()` method.\n\nCeases the flow of data.  No `'data'` events are emitted while the\nstream is in a paused state.\n\n### readable.resume()\n\nSwitches the readable stream into \"old mode\", where data is emitted\nusing a `'data'` event rather than being buffered for consumption via\nthe `read()` method.\n\nResumes the incoming `'data'` events after a `pause()`.\n\n\n## Class: stream.Writable\n\n<!--type=class-->\n\nA `Writable` Stream has the following methods, members, and events.\n\nNote that `stream.Writable` is an abstract class designed to be\nextended with an underlying implementation of the\n`_write(chunk, encoding, cb)` method. (See below.)\n\n### new stream.Writable([options])\n\n* `options` {Object}\n  * `highWaterMark` {Number} Buffer level when `write()` starts\n    returning false. Default=16kb\n  * `decodeStrings` {Boolean} Whether or not to decode strings into\n    Buffers before passing them to `_write()`.  Default=true\n\nIn classes that extend the Writable class, make sure to call the\nconstructor so that the buffering settings can be properly\ninitialized.\n\n### writable.\\_write(chunk, encoding, callback)\n\n* `chunk` {Buffer | String} The chunk to be written.  Will always\n  be a buffer unless the `decodeStrings` option was set to `false`.\n* `encoding` {String} If the chunk is a string, then this is the\n  encoding type.  Ignore chunk is a buffer.  Note that chunk will\n  **always** be a buffer unless the `decodeStrings` option is\n  explicitly set to `false`.\n* `callback` {Function} Call this function (optionally with an error\n  argument) when you are done processing the supplied chunk.\n\nAll Writable stream implementations must provide a `_write` method to\nsend data to the underlying resource.\n\nNote: **This function MUST NOT be called directly.**  It should be\nimplemented by child classes, and called by the internal Writable\nclass methods only.\n\nCall the callback using the standard `callback(error)` pattern to\nsignal that the write completed successfully or with an error.\n\nIf the `decodeStrings` flag is set in the constructor options, then\n`chunk` may be a string rather than a Buffer, and `encoding` will\nindicate the sort of string that it is.  This is to support\nimplementations that have an optimized handling for certain string\ndata encodings.  If you do not explicitly set the `decodeStrings`\noption to `false`, then you can safely ignore the `encoding` argument,\nand assume that `chunk` will always be a Buffer.\n\nThis method is prefixed with an underscore because it is internal to\nthe class that defines it, and should not be called directly by user\nprograms.  However, you **are** expected to override this method in\nyour own extension classes.\n\n\n### writable.write(chunk, [encoding], [callback])\n\n* `chunk` {Buffer | String} Data to be written\n* `encoding` {String} Optional.  If `chunk` is a string, then encoding\n  defaults to `'utf8'`\n* `callback` {Function} Optional.  Called when this chunk is\n  successfully written.\n* Returns {Boolean}\n\nWrites `chunk` to the stream.  Returns `true` if the data has been\nflushed to the underlying resource.  Returns `false` to indicate that\nthe buffer is full, and the data will be sent out in the future. The\n`'drain'` event will indicate when the buffer is empty again.\n\nThe specifics of when `write()` will return false, is determined by\nthe `highWaterMark` option provided to the constructor.\n\n### writable.end([chunk], [encoding], [callback])\n\n* `chunk` {Buffer | String} Optional final data to be written\n* `encoding` {String} Optional.  If `chunk` is a string, then encoding\n  defaults to `'utf8'`\n* `callback` {Function} Optional.  Called when the final chunk is\n  successfully written.\n\nCall this method to signal the end of the data being written to the\nstream.\n\n### Event: 'drain'\n\nEmitted when the stream's write queue empties and it's safe to write\nwithout buffering again. Listen for it when `stream.write()` returns\n`false`.\n\n### Event: 'close'\n\nEmitted when the underlying resource (for example, the backing file\ndescriptor) has been closed. Not all streams will emit this.\n\n### Event: 'finish'\n\nWhen `end()` is called and there are no more chunks to write, this\nevent is emitted.\n\n### Event: 'pipe'\n\n* `source` {Readable Stream}\n\nEmitted when the stream is passed to a readable stream's pipe method.\n\n### Event 'unpipe'\n\n* `source` {Readable Stream}\n\nEmitted when a previously established `pipe()` is removed using the\nsource Readable stream's `unpipe()` method.\n\n## Class: stream.Duplex\n\n<!--type=class-->\n\nA \"duplex\" stream is one that is both Readable and Writable, such as a\nTCP socket connection.\n\nNote that `stream.Duplex` is an abstract class designed to be\nextended with an underlying implementation of the `_read(size)`\nand `_write(chunk, encoding, callback)` methods as you would with a Readable or\nWritable stream class.\n\nSince JavaScript doesn't have multiple prototypal inheritance, this\nclass prototypally inherits from Readable, and then parasitically from\nWritable.  It is thus up to the user to implement both the lowlevel\n`_read(n)` method as well as the lowlevel `_write(chunk, encoding, cb)` method\non extension duplex classes.\n\n### new stream.Duplex(options)\n\n* `options` {Object} Passed to both Writable and Readable\n  constructors. Also has the following fields:\n  * `allowHalfOpen` {Boolean} Default=true.  If set to `false`, then\n    the stream will automatically end the readable side when the\n    writable side ends and vice versa.\n\nIn classes that extend the Duplex class, make sure to call the\nconstructor so that the buffering settings can be properly\ninitialized.\n\n## Class: stream.Transform\n\nA \"transform\" stream is a duplex stream where the output is causally\nconnected in some way to the input, such as a zlib stream or a crypto\nstream.\n\nThere is no requirement that the output be the same size as the input,\nthe same number of chunks, or arrive at the same time.  For example, a\nHash stream will only ever have a single chunk of output which is\nprovided when the input is ended.  A zlib stream will either produce\nmuch smaller or much larger than its input.\n\nRather than implement the `_read()` and `_write()` methods, Transform\nclasses must implement the `_transform()` method, and may optionally\nalso implement the `_flush()` method.  (See below.)\n\n### new stream.Transform([options])\n\n* `options` {Object} Passed to both Writable and Readable\n  constructors.\n\nIn classes that extend the Transform class, make sure to call the\nconstructor so that the buffering settings can be properly\ninitialized.\n\n### transform.\\_transform(chunk, encoding, callback)\n\n* `chunk` {Buffer | String} The chunk to be transformed.  Will always\n  be a buffer unless the `decodeStrings` option was set to `false`.\n* `encoding` {String} If the chunk is a string, then this is the\n  encoding type.  (Ignore if `decodeStrings` chunk is a buffer.)\n* `callback` {Function} Call this function (optionally with an error\n  argument) when you are done processing the supplied chunk.\n\nNote: **This function MUST NOT be called directly.**  It should be\nimplemented by child classes, and called by the internal Transform\nclass methods only.\n\nAll Transform stream implementations must provide a `_transform`\nmethod to accept input and produce output.\n\n`_transform` should do whatever has to be done in this specific\nTransform class, to handle the bytes being written, and pass them off\nto the readable portion of the interface.  Do asynchronous I/O,\nprocess things, and so on.\n\nCall `transform.push(outputChunk)` 0 or more times to generate output\nfrom this input chunk, depending on how much data you want to output\nas a result of this chunk.\n\nCall the callback function only when the current chunk is completely\nconsumed.  Note that there may or may not be output as a result of any\nparticular input chunk.\n\nThis method is prefixed with an underscore because it is internal to\nthe class that defines it, and should not be called directly by user\nprograms.  However, you **are** expected to override this method in\nyour own extension classes.\n\n### transform.\\_flush(callback)\n\n* `callback` {Function} Call this function (optionally with an error\n  argument) when you are done flushing any remaining data.\n\nNote: **This function MUST NOT be called directly.**  It MAY be implemented\nby child classes, and if so, will be called by the internal Transform\nclass methods only.\n\nIn some cases, your transform operation may need to emit a bit more\ndata at the end of the stream.  For example, a `Zlib` compression\nstream will store up some internal state so that it can optimally\ncompress the output.  At the end, however, it needs to do the best it\ncan with what is left, so that the data will be complete.\n\nIn those cases, you can implement a `_flush` method, which will be\ncalled at the very end, after all the written data is consumed, but\nbefore emitting `end` to signal the end of the readable side.  Just\nlike with `_transform`, call `transform.push(chunk)` zero or more\ntimes, as appropriate, and call `callback` when the flush operation is\ncomplete.\n\nThis method is prefixed with an underscore because it is internal to\nthe class that defines it, and should not be called directly by user\nprograms.  However, you **are** expected to override this method in\nyour own extension classes.\n\n### Example: `SimpleProtocol` parser\n\nThe example above of a simple protocol parser can be implemented much\nmore simply by using the higher level `Transform` stream class.\n\nIn this example, rather than providing the input as an argument, it\nwould be piped into the parser, which is a more idiomatic Node stream\napproach.\n\n```javascript\nfunction SimpleProtocol(options) {\n  if (!(this instanceof SimpleProtocol))\n    return new SimpleProtocol(options);\n\n  Transform.call(this, options);\n  this._inBody = false;\n  this._sawFirstCr = false;\n  this._rawHeader = [];\n  this.header = null;\n}\n\nSimpleProtocol.prototype = Object.create(\n  Transform.prototype, { constructor: { value: SimpleProtocol }});\n\nSimpleProtocol.prototype._transform = function(chunk, encoding, done) {\n  if (!this._inBody) {\n    // check if the chunk has a \\n\\n\n    var split = -1;\n    for (var i = 0; i < chunk.length; i++) {\n      if (chunk[i] === 10) { // '\\n'\n        if (this._sawFirstCr) {\n          split = i;\n          break;\n        } else {\n          this._sawFirstCr = true;\n        }\n      } else {\n        this._sawFirstCr = false;\n      }\n    }\n\n    if (split === -1) {\n      // still waiting for the \\n\\n\n      // stash the chunk, and try again.\n      this._rawHeader.push(chunk);\n    } else {\n      this._inBody = true;\n      var h = chunk.slice(0, split);\n      this._rawHeader.push(h);\n      var header = Buffer.concat(this._rawHeader).toString();\n      try {\n        this.header = JSON.parse(header);\n      } catch (er) {\n        this.emit('error', new Error('invalid simple protocol data'));\n        return;\n      }\n      // and let them know that we are done parsing the header.\n      this.emit('header', this.header);\n\n      // now, because we got some extra data, emit this first.\n      this.push(b);\n    }\n  } else {\n    // from there on, just provide the data to our consumer as-is.\n    this.push(b);\n  }\n  done();\n};\n\nvar parser = new SimpleProtocol();\nsource.pipe(parser)\n\n// Now parser is a readable stream that will emit 'header'\n// with the parsed header data.\n```\n\n\n## Class: stream.PassThrough\n\nThis is a trivial implementation of a `Transform` stream that simply\npasses the input bytes across to the output.  Its purpose is mainly\nfor examples and testing, but there are occasionally use cases where\nit can come in handy.\n\n\n[EventEmitter]: events.html#events_class_events_eventemitter\n",

The former tracks the Streams2 implementation in Node 0.10, including bug-fixes and minor improvements as they are added. The latter tracks Streams3 as it develops in Node 0.11; we will likely see a v1.2.x branch for Node 0.12.\n\n**readable-stream** uses proper patch-level versioning so if you pin to `\"~1.0.0\"` you’ll get the latest Node 0.10 Streams2 implementation, including any fixes and minor non-breaking improvements. The patch-level versions of 1.0.x and 1.1.x should mirror the patch-level versions of Node-core releases. You should prefer the **1.0.x** releases for now and when you’re ready to start using Streams3, pin to `\"~1.1.0\"`\n\n",

+# 1.7.0
+
+2014-02-27
+
+ - Add support for rulesets in variables and passed to mixins to allow wrapping
+ - Change luma to follow the w3c spec, luma is available as luminance. Contrast still uses luma so you may see differences if your threshold % is close to the existing calculated luma.
+ - Upgraded clean css which means the --selectors-merge-mode is now renamed --compatibility
+ - Add support for using variables with @keyframes, @namespace, @charset
+ - Support property merging with +_ when spaces are needed and keep + for comma separated
+ - Imports now always import once consistently - a race condition meant previously certain configurations would lead to a different ordering of files
+ - Fix support for `.mixin(@args...)` when called with no args (e.g. `.mixin();`)
+ - Do unit conversions with min and max functions. Don't pass through if not understood, throw an error
+ - Allow % to be passed on its own to the unit function e.g. `unit(10, %)`
+ - Fix a bug when comparing a unit value to a non-unit value if the unit-value was the multiple of another unit (e.g. cm, mm, deg etc.)
+ - Fix mixins with media queries in import reference files not being put into the output (they now output, they used to incorrectly not)
+ - Fix lint mode - now reports all errors
+ - Fixed a small scope issue with & {} selector rulesets incorrectly making mixins visible - regression from 1.6.2
+ - Browser - added log level "debug" at 3 to get less logging, The default has changed so unless you set the value to the default you won't see a difference
+ - Browser - logLevel takes effect regardless of the environment (production/dev)
+ - Browser - added postProcessor option, a function called to post-process the css before adding to the page
+ - Browser - use the right request for file access in IE
+
+# 1.6.3

-# [Less.js v1.6.2](http://lesscss.org)
-
-> The **dynamic** stylesheet language. [http://lesscss.org](http://lesscss.org).
-
-This is the JavaScript, and now official, stable version of LESS.
-
-
-## Getting Started
-
-Options for adding Less.js to your project:
-
-* Install with [NPM](https://npmjs.org/): `npm install less`
-* [Download the latest release][download]
-* Clone the repo: `git clone git://github.com/less/less.js.git`
-
-
-
-## Feature Highlights
-LESS extends CSS with dynamic features such as:
-
-* [nesting](#nesting)
-* [variables](#variables)
-* [operations](#operations)
-* [mixins](#mixins)
-* [extend](#extend) (selector inheritance)
-
-To learn about the many other features Less.js has to offer please visit [http://lesscss.org](http://lesscss.org) and [the Less.js wiki][wiki]
-
-
-### Examples
-#### nesting
-Take advantage of nesting to make code more readable and maintainable. This:
-
-```less
-.nav > li > a {
-  border: 1px solid #f5f5f5;
-  &:hover {
-    border-color: #ddd;
-  }
-}
-```
-
-renders to:
-
-```css
-.nav > li > a {
-  border: 1px solid #f5f5f5;
-}
-.nav > li > a:hover {
-  border-color: #ddd;
-}
-```
-
-
-#### variables
-Updated commonly used values from a single location.
-
-```less
-// Variables ("inline" comments like this can be used)
-@link-color:  #428bca; // appears as "sea blue"
-
-/* Or "block comments" that span
-   multiple lines, like this */
-a {
-  color: @link-color; // use the variable in styles
-}
-```
-
-Variables can also be used in `@import` statements, URLs, selector names, and more.
-
-
-
-#### operations
-Continuing with the same example above, we can use our variables even easier to maintain with _operations_, which enables the use of addition, subraction, multiplication and division in your styles:
-
-```less
-// Variables
-@link-color:        #428bca;
-@link-color-hover:  darken(@link-color, 10%);
-
-// Styles
-a {
-  color: @link-color;
-}
-a:hover {
-  color: @link-color-hover;
-}
-```
-renders to:
-
-```css
-a {
-  color: #428bca;
-}
-a:hover {
-  color: #3071a9;
-}
-```
-
-#### mixins
-##### "implicit" mixins
-Mixins enable you to apply the styles of one selector inside another selector like this:
-
-```less
-// Variables
-@link-color:        #428bca;
-
-// Any "regular" class...
-.link {
-  color: @link-color;
-}
-a {
-  font-weight: bold;
-  .link; // ...can be used as an "implicit" mixin
-}
-```
-
-renders to:
-
-```css
-.link {
-  color: #428bca;
-}
-a {
-  font-weight: bold;
-  color: #428bca;
-}
-```
-
-So any selector can be an "implicit mixin". We'll show you a DRYer way to do this below.
-
-
-
-##### parametric mixins
-Mixins can also accept parameters:
-
-```less
-// Transition mixin
-.transition(@transition) {
-  -webkit-transition: @transition;
-     -moz-transition: @transition;
-       -o-transition: @transition;
-          transition: @transition;
-}
-```
-
-used like this:
-
-```less
-// Variables
-@link-color:        #428bca;
-@link-color-hover:  darken(@link-color, 10%);
-
-//Transition mixin would be anywhere here
-
-a {
-  font-weight: bold;
-  color: @link-color;
-  .transition(color .2s ease-in-out);
-  // Hover state
-  &:hover {
-    color: @link-color-hover;
-  }
-}
-```
-
-renders to:
-
-```css
-a {
-  font-weight: bold;
-  color: #428bca;
-  -webkit-transition: color 0.2s ease-in-out;
-     -moz-transition: color 0.2s ease-in-out;
-       -o-transition: color 0.2s ease-in-out;
-          transition: color 0.2s ease-in-out;
-}
-a:hover {
-  color: #3071a9;
-}
-```
-
-
-#### extend
-The `extend` feature can be thought of as the _inverse_ of mixins. It accomplishes the goal of "borrowing styles", but rather than copying all the rules of _Selector A_ over to _Selector B_, `extend` copies the name of the _inheriting selector_ (_Selector B_) over to the _extending selector_ (_Selector A_). So continuing with the example used for [mixins](#mixins) above, extend works like this:
-
-```less
-// Variables
-@link-color:        #428bca;
-
-.link {
-  color: @link-color;
-}
-a:extend(.link) {
-  font-weight: bold;
-}
-// Can also be written as
-a {
-  &:extend(.link);
-  font-weight: bold;
-}
-```
-
-renders to:
-
-```css
-.link, a {
-  color: #428bca;
-}
-a {
-  font-weight: bold;
-}
-```
-
-## Usage
-
-### Compiling and Parsing
-Invoke the compiler from node:
-
-```javascript
-var less = require('less');
-
-less.render('.class { width: (1 + 1) }', function (e, css) {
-    console.log(css);
-});
-```
-
-Outputs:
-
-```css
-.class {
-  width: 2;
-}
-```
-
-You may also manually invoke the parser and compiler:
-
-```javascript
-var parser = new(less.Parser);
-
-parser.parse('.class { width: (1 + 1) }', function (err, tree) {
-    if (err) { return console.error(err) }
-    console.log(tree.toCSS());
-});
-```
-
-
-### Configuration
-You may also pass options to the compiler:
-
-```javascript
-var parser = new(less.Parser)({
-    paths: ['.', './src/less'], // Specify search paths for @import directives
-    filename: 'style.less'      // Specify a filename, for better error messages
-});
-
-parser.parse('.class { width: (1 + 1) }', function (e, tree) {
-    tree.toCSS({ compress: true }); // Minify CSS output
-});
-```
-
-## More information

-
-Here are other resources for using Less.js:
-
-* [stackoverflow.com][so] is a great place to get answers about Less.
-* [node.js tools](https://github.com/less/less.js/wiki/Converting-LESS-to-CSS) for converting Less to CSS
-* [GUI compilers for Less](https://github.com/less/less.js/wiki/GUI-compilers-that-use-LESS.js)
-* [Less.js Issues][issues] for reporting bugs
-
-
-
-## Contributing
-Please read [CONTRIBUTING.md](./CONTRIBUTING.md). Add unit tests for any new or changed functionality. Lint and test your code using [Grunt](http://gruntjs.com/).
-
-### Reporting Issues
-
-Before opening any issue, please search for existing issues and read the [Issue Guidelines](https://github.com/necolas/issue-guidelines), written by [Nicolas Gallagher](https://github.com/necolas/). After that if you find a bug or would like to make feature request, [please open a new issue][issues].
-
-Please report documentation issues in [the documentation project](https://github.com/less/less-docs).
-
-### Development
-
-#### Install Less.js
-
-Start by either [downloading this project][download] manually, or in the command line:
-
-```shell
-git clone https://github.com/less/less.js.git "less"
-```
-and then `cd less`.
-
-
-#### Install dependencies
-
-To install all the dependencies for less development, run:
-
-```shell
-npm install
-```
-
-If you haven't run grunt before, install grunt-cli globally so you can just run `grunt`
-
-```shell
-npm install grunt-cli -g
-```
-
-You should now be able to build Less.js, run tests, benchmarking, and other tasks listed in the Gruntfile.
-
-## Using Less.js Grunt
-
-Tests, benchmarking and building is done using Grunt `~0.4.1`. If you haven't used [Grunt](http://gruntjs.com/) before, be sure to check out the [Getting Started](http://gruntjs.com/getting-started) guide, as it explains how to install and use Grunt plugins, which are necessary for development with Less.js.
-
-The Less.js [Gruntfile](Gruntfile.js) is configured with the following "convenience tasks" :
-
-#### test - `grunt`
-Runs jshint, nodeunit and headless jasmine tests using [phantomjs](http://code.google.com/p/phantomjs/). You must have phantomjs installed for the jasmine tests to run.
-
-#### test - `grunt benchmark`
-Runs the benchmark suite.
-
-#### build for testing browser - 'grunt browser'
-This builds less.js and puts it in 'test/browser/less.js'
-
-#### build - `grunt stable | grunt beta | grunt alpha`
-Builds Less.js from from the `/lib/less` source files. This is done by the developer releasing a new release, do not do this if you are creating a pull request.
-
-#### readme - `grunt readme`
-Build the README file from [a template](build/README.md) to ensure that metadata is up-to-date and (more likely to be) correct.
-
-Please review the [Gruntfile](Gruntfile.js) to become acquainted with the other available tasks.
-
-**Please note** that if you have any issues installing dependencies or running any of the Gruntfile commands, please make sure to uninstall any previous versions, both in the local node_modules directory, and clear your global npm cache, and then try running `npm install` again. After that if you still have issues, please let us know about it so we can help.

-Take advantage of nesting to make code more readable and maintainable. This:
-
-```less
-.nav > li > a {
-  border: 1px solid #f5f5f5;
-  &:hover {
-    border-color: #ddd;
-  }
-}
-```
-
-renders to:
-
-```css
-.nav > li > a {
-  border: 1px solid #f5f5f5;
-}
-.nav > li > a:hover {
-  border-color: #ddd;
-}
-```
-
-
-#### variables
-Updated commonly used values from a single location.
-
-```less
-// Variables ("inline" comments like this can be used)
-@link-color:  #428bca; // appears as "sea blue"
-
-/* Or "block comments" that span
-   multiple lines, like this */
-a {
-  color: @link-color; // use the variable in styles
-}
-```
-
-Variables can also be used in `@import` statements, URLs, selector names, and more.
-
-
-
-#### operations
-Continuing with the same example above, we can use our variables even easier to maintain with _operations_, which enables the use of addition, subraction, multiplication and division in your styles:
-
-```less
-// Variables
-@link-color:        #428bca;
-@link-color-hover:  darken(@link-color, 10%);
-
-// Styles
-a {
-  color: @link-color;
-}
-a:hover {
-  color: @link-color-hover;
-}
-```
-renders to:
-
-```css
-a {
-  color: #428bca;
-}
-a:hover {
-  color: #3071a9;
-}
-```
-
-#### mixins
-##### "implicit" mixins
-Mixins enable you to apply the styles of one selector inside another selector like this:
-
-```less
-// Variables
-@link-color:        #428bca;
-
-// Any "regular" class...
-.link {
-  color: @link-color;
-}
-a {
-  font-weight: bold;
-  .link; // ...can be used as an "implicit" mixin
-}
-```
-
-renders to:
-
-```css
-.link {
-  color: #428bca;
-}
-a {
-  font-weight: bold;
-  color: #428bca;
-}
-```
-
-So any selector can be an "implicit mixin". We'll show you a DRYer way to do this below.
-
-
-
-##### parametric mixins
-Mixins can also accept parameters:
-
-```less
-// Transition mixin
-.transition(@transition) {
-  -webkit-transition: @transition;
-     -moz-transition: @transition;
-       -o-transition: @transition;
-          transition: @transition;
-}
-```
-
-used like this:
-
-```less
-// Variables
-@link-color:        #428bca;
-@link-color-hover:  darken(@link-color, 10%);
-
-//Transition mixin would be anywhere here
-
-a {
-  font-weight: bold;
-  color: @link-color;
-  .transition(color .2s ease-in-out);
-  // Hover state
-  &:hover {
-    color: @link-color-hover;
-  }
-}
-```
-
-renders to:
-
-```css
-a {
-  font-weight: bold;
-  color: #428bca;
-  -webkit-transition: color 0.2s ease-in-out;
-     -moz-transition: color 0.2s ease-in-out;
-       -o-transition: color 0.2s ease-in-out;
-          transition: color 0.2s ease-in-out;
-}
-a:hover {
-  color: #3071a9;
-}
-```
-
-
-#### extend
-The `extend` feature can be thought of as the _inverse_ of mixins. It accomplishes the goal of "borrowing styles", but rather than copying all the rules of _Selector A_ over to _Selector B_, `extend` copies the name of the _inheriting selector_ (_Selector B_) over to the _extending selector_ (_Selector A_). So continuing with the example used for [mixins](#mixins) above, extend works like this:
-
-```less
-// Variables
-@link-color:        #428bca;
-
-.link {
-  color: @link-color;
-}
-a:extend(.link) {
-  font-weight: bold;
-}
-// Can also be written as
-a {
-  &:extend(.link);
-  font-weight: bold;
-}
-```
-
-renders to:
-
-```css
-.link, a {
-  color: #428bca;
-}
-a {
-  font-weight: bold;
-}
-```
-
-## Usage
-
-### Compiling and Parsing
-Invoke the compiler from node:
-
-```javascript
-var less = require('less');
-
-less.render('.class { width: (1 + 1) }', function (e, css) {
-    console.log(css);
-});
-```
-
-Outputs:
-
-```css
-.class {
-  width: 2;
-}
-```
-
-You may also manually invoke the parser and compiler:
-
-```javascript
-var parser = new(less.Parser);
-
-parser.parse('.class { width: (1 + 1) }', function (err, tree) {
-    if (err) { return console.error(err) }
-    console.log(tree.toCSS());
-});
-```
-
-
-### Configuration
-You may also pass options to the compiler:
-
-```javascript
-var parser = new(less.Parser)({
-    paths: ['.', './src/less'], // Specify search paths for @import directives
-    filename: 'style.less'      // Specify a filename, for better error messages
-});
-
-parser.parse('.class { width: (1 + 1) }', function (e, tree) {
-    tree.toCSS({ compress: true }); // Minify CSS output
-});
-```
-

 ### Development
 
-#### Install Less.js
-
-Start by either [downloading this project][download] manually, or in the command line:
-
-```shell
-git clone https://github.com/less/less.js.git "less"
-```
-and then `cd less`.
-
-
-#### Install dependencies
-
-To install all the dependencies for less development, run:
-
-```shell
-npm install
-```
-
-If you haven't run grunt before, install grunt-cli globally so you can just run `grunt`
-
-```shell
-npm install grunt-cli -g
-```
-
-You should now be able to build Less.js, run tests, benchmarking, and other tasks listed in the Gruntfile.
-
-## Using Less.js Grunt
-
-Tests, benchmarking and building is done using Grunt `<%= pkg.devDependencies.grunt %>`. If you haven't used [Grunt](http://gruntjs.com/) before, be sure to check out the [Getting Started](http://gruntjs.com/getting-started) guide, as it explains how to install and use Grunt plugins, which are necessary for development with Less.js.
-
-The Less.js [Gruntfile](Gruntfile.js) is configured with the following "convenience tasks" :
-
-#### test - `grunt`
-Runs jshint, nodeunit and headless jasmine tests using [phantomjs](http://code.google.com/p/phantomjs/). You must have phantomjs installed for the jasmine tests to run.
-
-#### test - `grunt benchmark`
-Runs the benchmark suite.
-
-#### build for testing browser - 'grunt browser'
-This builds less.js and puts it in 'test/browser/less.js'
-
-#### build - `grunt stable | grunt beta | grunt alpha`
-Builds Less.js from from the `/lib/less` source files. This is done by the developer releasing a new release, do not do this if you are creating a pull request.
-
-#### readme - `grunt readme`
-Build the README file from [a template](build/README.md) to ensure that metadata is up-to-date and (more likely to be) correct.
-
-Please review the [Gruntfile](Gruntfile.js) to become acquainted with the other available tasks.
-
-**Please note** that if you have any issues installing dependencies or running any of the Gruntfile commands, please make sure to uninstall any previous versions, both in the local node_modules directory, and clear your global npm cache, and then try running `npm install` again. After that if you still have issues, please let us know about it so we can help.

+// less.js - parser
+//
+//    A relatively straight-forward predictive parser.
+//    There is no tokenization/lexing stage, the input is parsed
+//    in one sweep.
+//
+//    To make the parser fast enough to run in the browser, several
+//    optimization had to be made:
+//
+//    - Matching and slicing on a huge input is often cause of slowdowns.
+//      The solution is to chunkify the input into smaller strings.
+//      The chunks are stored in the `chunks` var,
+//      `j` holds the current chunk index, and `currentPos` holds
+//      the index of the current chunk in relation to `input`.
+//      This gives us an almost 4x speed-up.
+//
+//    - In many cases, we don't need to match individual tokens;
+//      for example, if a value doesn't hold any variables, operations
+//      or dynamic references, the parser can effectively 'skip' it,
+//      treating it as a literal.
+//      An example would be '1px solid #000' - which evaluates to itself,
+//      we don't need to know what the individual components are.
+//      The drawback, of course is that you don't get the benefits of
+//      syntax-checking on the CSS. This gives us a 50% speed-up in the parser,
+//      and a smaller speed-up in the code-gen.
+//
+//
+//    Token matching is done with the `$` function, which either takes
+//    a terminal string or regexp, or a non-terminal function to call.
+//    It also takes care of moving all the indices forwards.
+//

+        //         Rule ("color",  Value ([Expression [Color #fff]]))

+        //
+        //  In general, most rules will try to parse a token with the `$()` function, and if the return
+        //  value is truly, will return a new node, of the relevant type. Sometimes, we need to check

+// less.js - parser
+//
+//    A relatively straight-forward predictive parser.
+//    There is no tokenization/lexing stage, the input is parsed
+//    in one sweep.
+//
+//    To make the parser fast enough to run in the browser, several
+//    optimization had to be made:
+//
+//    - Matching and slicing on a huge input is often cause of slowdowns.
+//      The solution is to chunkify the input into smaller strings.
+//      The chunks are stored in the `chunks` var,
+//      `j` holds the current chunk index, and `currentPos` holds
+//      the index of the current chunk in relation to `input`.
+//      This gives us an almost 4x speed-up.
+//
+//    - In many cases, we don't need to match individual tokens;
+//      for example, if a value doesn't hold any variables, operations
+//      or dynamic references, the parser can effectively 'skip' it,
+//      treating it as a literal.
+//      An example would be '1px solid #000' - which evaluates to itself,
+//      we don't need to know what the individual components are.
+//      The drawback, of course is that you don't get the benefits of
+//      syntax-checking on the CSS. This gives us a 50% speed-up in the parser,
+//      and a smaller speed-up in the code-gen.
+//
+//
+//    Token matching is done with the `$` function, which either takes
+//    a terminal string or regexp, or a non-terminal function to call.
+//    It also takes care of moving all the indices forwards.
+//
+//

+//    A relatively straight-forward predictive parser.
+//    There is no tokenization/lexing stage, the input is parsed
+//    in one sweep.
+//
+//    To make the parser fast enough to run in the browser, several
+//    optimization had to be made:
+//
+//    - Matching and slicing on a huge input is often cause of slowdowns.
+//      The solution is to chunkify the input into smaller strings.
+//      The chunks are stored in the `chunks` var,
+//      `j` holds the current chunk index, and `currentPos` holds
+//      the index of the current chunk in relation to `input`.
+//      This gives us an almost 4x speed-up.
+//
+//    - In many cases, we don't need to match individual tokens;
+//      for example, if a value doesn't hold any variables, operations
+//      or dynamic references, the parser can effectively 'skip' it,
+//      treating it as a literal.
+//      An example would be '1px solid #000' - which evaluates to itself,
+//      we don't need to know what the individual components are.
+//      The drawback, of course is that you don't get the benefits of
+//      syntax-checking on the CSS. This gives us a 50% speed-up in the parser,
+//      and a smaller speed-up in the code-gen.
+//
+//
+//    Token matching is done with the `$` function, which either takes
+//    a terminal string or regexp, or a non-terminal function to call.
+//    It also takes care of moving all the indices forwards.

+//    A relatively straight-forward predictive parser.
+//    There is no tokenization/lexing stage, the input is parsed
+//    in one sweep.
+//
+//    To make the parser fast enough to run in the browser, several
+//    optimization had to be made:
+//
+//    - Matching and slicing on a huge input is often cause of slowdowns.
+//      The solution is to chunkify the input into smaller strings.
+//      The chunks are stored in the `chunks` var,
+//      `j` holds the current chunk index, and `currentPos` holds
+//      the index of the current chunk in relation to `input`.
+//      This gives us an almost 4x speed-up.
+//
+//    - In many cases, we don't need to match individual tokens;
+//      for example, if a value doesn't hold any variables, operations
+//      or dynamic references, the parser can effectively 'skip' it,
+//      treating it as a literal.
+//      An example would be '1px solid #000' - which evaluates to itself,
+//      we don't need to know what the individual components are.
+//      The drawback, of course is that you don't get the benefits of
+//      syntax-checking on the CSS. This gives us a 50% speed-up in the parser,
+//      and a smaller speed-up in the code-gen.
+//
+//
+//    Token matching is done with the `$` function, which either takes
+//    a terminal string or regexp, or a non-terminal function to call.
+//    It also takes care of moving all the indices forwards.

+1. Fork it.
+2. Add test(s) veryfying the problem.
+3. Fix the problem.
+4. Make sure all tests still pass (`npm test`).
+5. Make sure your code doesn't break style rules (`npm run check`).
+6. Send a PR.

+If you wonder where to add tests, go for:
+
+* `test/unit-test.js` if it's a simple scenario
+* `test/data/...` if it's a complex scenario (just add two files, input and expected output)
+* `test/binary-test.js` if it's related to `bin/cleancss` binary
+* `test/module-test.js` if it's related to importing `clean-css` as a module

The example below parses args and options from `process.argv`, leaving remaining args as the `program.args` array which were not consumed by options.\n\n```js\n#!/usr/bin/env node\n\n/**\n * Module dependencies.\n */\n\nvar program = require('commander');\n\nprogram\n  .version('0.0.1')\n  .option('-p, --peppers', 'Add peppers')\n  .option('-P, --pineapple', 'Add pineapple')\n  .option('-b, --bbq', 'Add bbq sauce')\n  .option('-c, --cheese [type]', 'Add the specified type of cheese [marble]', 'marble')\n  .parse(process.argv);\n\nconsole.log('you ordered a pizza with:');\nif (program.peppers) console.log('  - peppers');\nif (program.pineapple) console.log('  - pineapple');\nif (program.bbq) console.log('  - bbq');\nconsole.log('  - %s cheese', program.cheese);\n```\n\n Short flags may be passed as a single arg, for example `-abc` is equivalent to `-a -b -c`. Multi-word options such as \"--template-engine\" are camel-cased, becoming `program.templateEngine` etc.\n\n## Automated --help\n\n The help information is auto-generated based on the information commander already knows about your program, so the following `--help` info is for free:\n\n```  \n $ ./examples/pizza --help\n\n   Usage: pizza [options]\n\n   Options:\n\n     -V, --version        output the version number\n     -p, --peppers        Add peppers\n     -P, --pineapple      Add pineapple\n     -b, --bbq            Add bbq sauce\n     -c, --cheese <type>  Add the specified type of cheese [marble]\n     -h, --help           output usage information\n\n```\n\n## Coercion\n\n```js\nfunction range(val) {\n  return val.split('..').map(Number);\n}\n\nfunction list(val) {\n  return val.split(',');\n}\n\nprogram\n  .version('0.0.1')\n  .usage('[options] <file ...>')\n  .option('-i, --integer <n>', 'An integer argument', parseInt)\n  .option('-f, --float <n>', 'A float argument', parseFloat)\n  .option('-r, --range <a>..<b>', 'A range', range)\n  .option('-l, --list <items>', 'A list', list)\n  .option('-o, --optional [value]', 'An optional value')\n  .parse(process.argv);\n\nconsole.log(' int: %j', program.integer);\nconsole.log(' float: %j', program.float);\nconsole.log(' optional: %j', program.optional);\nprogram.range = program.range || [];\nconsole.log(' range: %j..%j', program.range[0], program.range[1]);\nconsole.log(' list: %j', program.list);\nconsole.log(' args: %j', program.args);\n```\n\n## Custom help\n\n You can display arbitrary `-h, --help` information\n by listening for \"--help\". Commander will automatically\n exit once you are done so that the remainder of your program\n does not execute causing undesired behaviours, for example\n in the following executable \"stuff\" will not output when\n `--help` is used.\n\n```js\n#!/usr/bin/env node\n\n/**\n * Module dependencies.\n */\n\nvar program = require('../');\n\nfunction list(val) {\n  return val.split(',').map(Number);\n}\n\nprogram\n  .version('0.0.1')\n  .option('-f, --foo', 'enable some foo')\n  .option('-b, --bar', 'enable some bar')\n  .option('-B, --baz', 'enable some baz');\n\n// must be before .parse() since\n// node's emit() is immediate\n\nprogram.on('--help', function(){\n  console.log('  Examples:');\n  console.log('');\n  console.log('    $ custom-help --help');\n  console.log('    $ custom-help -h');\n  console.log('');\n});\n\nprogram.parse(process.argv);\n\nconsole.log('stuff');\n```\n\nyielding the following help output:\n\n```\n\nUsage: custom-help [options]\n\nOptions:\n\n  -h, --help     output usage information\n  -V, --version  output the version number\n  -f, --foo      enable some foo\n  -b, --bar      enable some bar\n  -B, --baz      enable some baz\n\nExamples:\n\n  $ custom-help --help\n  $ custom-help -h\n\n```\n\n## .outputHelp()\n\n  Output help information without exiting.\n\n## .help()\n\n  Output help information and exit immediately.\n\n## Links\n\n - [API documentation](http://visionmedia.github.com/commander.js/)\n - [ascii tables](https://github.com/LearnBoost/cli-table)\n - [progress bars](https://github.com/visionmedia/node-progress)\n - [more progress bars](https://github.com/substack/node-multimeter)\n - [examples](https://github.com/visionmedia/commander.js/tree/master/examples)\n\n## License \n\n(The MIT License)\n\nCopyright (c) 2011 TJ Holowaychuk &lt;tj@vision-media.ca&gt;\n\nPermission is hereby granted, free of charge, to any person obtaining\na copy of this software and associated documentation files (the\n'Software'), to deal in the Software without restriction, including\nwithout limitation the rights to use, copy, modify, merge, publish,\ndistribute, sublicense, and/or sell copies of the Software, and to\npermit persons to whom the Software is furnished to do so, subject to\nthe following conditions:\n\nThe above copyright notice and this permission notice shall be\nincluded in all copies or substantial portions of the Software.\n\nTHE SOFTWARE IS PROVIDED 'AS IS', WITHOUT WARRANTY OF ANY KIND,\nEXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF\nMERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT.\nIN NO EVENT SHALL THE AUTHORS OR COPYRIGHT HOLDERS BE LIABLE FOR ANY\nCLAIM, DAMAGES OR OTHER LIABILITY, WHETHER IN AN ACTION OF CONTRACT,\nTORT OR OTHERWISE, ARISING FROM, OUT OF OR IN CONNECTION WITH THE\nSOFTWARE OR THE USE OR OTHER DEALINGS IN THE SOFTWARE.\n",

That's it!\n\n#### Node.js module\n\nUpdate `clean-css` as for CLI above.\nThen change your JavaScript code from:\n\n```js\nvar minimized = CleanCSS.process(source, options);\n```\n\ninto\n\n```js\nvar minimized = new CleanCSS(options).minify(source);\n```\n\nAnd you are done.\n\n### How to use clean-css CLI?\n\nClean-css accepts the following command line arguments (please make sure\nyou use `<source-file>` as the very last argument to avoid potential issues):\n\n```\ncleancss [options] <source-file>\n\n-h, --help                      Output usage information\n-v, --version                   Output the version number\n-b, --keep-line-breaks          Keep line breaks\n--s0                            Remove all special comments, i.e. /*! comment */\n--s1                            Remove all special comments but the first one\n-r, --root [root-path]          A root path to which resolve absolute @import rules\n                                and rebase relative URLs\n-o, --output [output-file]      Use [output-file] as output instead of STDOUT\n-s, --skip-import               Disable @import processing\n--skip-rebase                   Disable URLs rebasing\n--skip-advanced                 Disable advanced optimizations - selector & property merging,\n                                reduction, etc.\n--selectors-merge-mode [ie8|*]  Use `ie8` for compatibility mode, `*` for merge all (default)\n-d, --debug                     Shows debug information (minification time & compression efficiency)\n```\n\n#### Examples:\n\nTo minify a **public.css** file into **public-min.css** do:\n\n```\ncleancss -o public-min.css public.css\n```\n\nTo minify the same **public.css** into the standard output skip the `-o` parameter:\n\n```\ncleancss public.css\n```\n\nMore likely you would like to concatenate a couple of files.\nIf you are on a Unix-like system:\n\n```bash\ncat one.css two.css three.css | cleancss -o merged-and-minified.css\n```\n\nOn Windows:\n\n```bat\ntype one.css two.css three.css | cleancss -o merged-and-minified.css\n```\n\nOr even gzip the result at once:\n\n```bash\ncat one.css two.css three.css | cleancss | gzip -9 -c > merged-minified-and-gzipped.css.gz\n```\n\n### How to use clean-css programmatically?\n\n```js\nvar CleanCSS = require('clean-css');\nvar source = 'a{font-weight:bold;}';\nvar minimized = new CleanCSS().minify(source);\n```\n\nCleanCSS constructor accepts a hash as a parameter, i.e.,\n`new CleanCSS(options).minify(source)` with the following options available:\n\n* `keepSpecialComments` - `*` for keeping all (default), `1` for keeping first one only, `0` for removing all\n* `keepBreaks` - whether to keep line breaks (default is false)\n* `benchmark` - turns on benchmarking mode measuring time spent on cleaning up\n  (run `npm run bench` to see example)\n* `root` - path to resolve absolute `@import` rules and rebase relative URLs\n* `relativeTo` - path with which to resolve relative `@import` rules and URLs\n* `processImport` - whether to process `@import` rules\n* `noRebase` - whether to skip URLs rebasing\n* `noAdvanced` - set to true to disable advanced optimizations - selector & property merging, reduction, etc.\n* `selectorsMergeMode` - `ie8` for IE8 compatibility mode, `*` for merging all (default)\n* `debug` - set to true to get minification statistics under `stats` property (see `test/custom-test.js` for examples)\n\n### What are the clean-css' dev commands?\n\nFirst clone the source, then run:\n\n* `npm run bench` for clean-css benchmarks (see [test/bench.js](https://github.com/GoalSmashers/clean-css/blob/master/test/bench.js) for details)\n* `npm run check` to check JS sources with [JSHint](https://github.com/jshint/jshint/)\n* `npm test` for the test suite\n\n## Tips & Tricks\n\n### How to preserve a comment block?\n\nUse the `/*!` notation instead of the standard one `/*`:\n\n```css\n/*!\n  Important comments included in minified output.\n*/\n```\n\n### How to rebase relative image URLs\n\nClean-css will handle it automatically for you (since version 1.1) in the following cases:\n\n* When using the CLI:\n  1. Use an output path via `-o`/`--output` to rebase URLs as relative to the output file.\n  2. Use a root path via `-r`/`--root` to rebase URLs as absolute from the given root path.\n  3. If you specify both then `-r`/`--root` takes precendence.\n* When using clean-css as a library:\n  1. Use a combination of `relativeTo` and `target` options for relative rebase (same as 1 in CLI).\n  2. Use a combination of `relativeTo` and `root` options for absolute rebase (same as 2 in CLI).\n  3. `root` takes precendence over `target` as in CLI.\n\n## Acknowledgments\n\n* Vincent Voyer ([@vvo](https://github.com/vvo)) for a patch with better\n  empty element regex and for inspiring us to do many performance improvements\n  in 0.4 release.\n* Isaac ([@facelessuser](https://github.com/facelessuser)) for pointing out\n  a flaw in clean-css' stateless mode.\n* Jan Michael Alonzo ([@jmalonzo](https://github.com/jmalonzo)) for a patch\n  removing node.js' old `sys` package.\n* [@XhmikosR](https://github.com/XhmikosR) for suggesting new features\n  (option to remove special comments and strip out URLs quotation) and\n  pointing out numerous improvements (JSHint, media queries).\n* Anthony Barre ([@abarre](https://github.com/abarre)) for improvements to\n  `@import` processing, namely introducing the `--skip-import` /\n  `processImport` options.\n* Simon Altschuler ([@altschuler](https://github.com/altschuler)) for fixing\n  `@import` processing inside comments.\n\n## License\n\nClean-css is released under the [MIT License](https://github.com/GoalSmashers/clean-css/blob/master/LICENSE).\n",

+## UNIX Socket 
+
+`request` supports the `unix://` protocol for all requests. The path is assumed to be absolute to the root of the host file system. 
+
+HTTP paths are extracted from the supplied URL by testing each level of the full URL against net.connect for a socket response.

 ## Forms
 
 `request` supports `application/x-www-form-urlencoded` and `multipart/form-data` form uploads. For `multipart/related` refer to the `multipart` API.

+
+A robust Punycode converter that fully complies to [RFC 3492](http://tools.ietf.org/html/rfc3492) and [RFC 5891](http://tools.ietf.org/html/rfc5891), and works on nearly all JavaScript platforms.
+
+This JavaScript library is the result of comparing, optimizing and documenting different open-source implementations of the Punycode algorithm:

+
+This project is [bundled](https://github.com/joyent/node/blob/master/lib/punycode.js) with [Node.js v0.6.2+](https://github.com/joyent/node/compare/975f1930b1...61e796decc).
+
+## Installation
+
+Via [npm](http://npmjs.org/) (only required for Node.js releases older than v0.6.2):
+
+```bash
+npm install punycode
+```
+
+Via [Bower](http://bower.io/):
+
+```bash
+bower install punycode
+```
+
+Via [Component](https://github.com/component/component):
+
+```bash
+component install bestiejs/punycode.js
+```
+
+In a browser:
+
+```html
+<script src="punycode.js"></script>
+```
+
+In [Narwhal](http://narwhaljs.org/), [Node.js](http://nodejs.org/), and [RingoJS](http://ringojs.org/):
+
+```js
+var punycode = require('punycode');
+```
+
+In [Rhino](http://www.mozilla.org/rhino/):
+
+```js
+load('punycode.js');
+```
+
+Using an AMD loader like [RequireJS](http://requirejs.org/):
+
+```js
+require(
+  {
+    'paths': {
+      'punycode': 'path/to/punycode'
+    }
+  },
+  ['punycode'],
+  function(punycode) {
+    console.log(punycode);
+  }
+);
+```
+
+## API
+
+### `punycode.decode(string)`
+
+Converts a Punycode string of ASCII symbols to a string of Unicode symbols.
+
+```js
+// decode domain name parts
+punycode.decode('maana-pta'); // 'mañana'
+punycode.decode('--dqo34k'); // '☃-⌘'
+```
+
+### `punycode.encode(string)`
+
+Converts a string of Unicode symbols to a Punycode string of ASCII symbols.
+
+```js
+// encode domain name parts
+punycode.encode('mañana'); // 'maana-pta'
+punycode.encode('☃-⌘'); // '--dqo34k'
+```
+
+### `punycode.toUnicode(domain)`
+
+Converts a Punycode string representing a domain name to Unicode. Only the Punycoded parts of the domain name will be converted, i.e. it doesn’t matter if you call it on a string that has already been converted to Unicode.
+
+```js
+// decode domain names
+punycode.toUnicode('xn--maana-pta.com'); // 'mañana.com'
+punycode.toUnicode('xn----dqo34k.com'); // '☃-⌘.com'
+```
+
+### `punycode.toASCII(domain)`
+
+Converts a Unicode string representing a domain name to Punycode. Only the non-ASCII parts of the domain name will be converted, i.e. it doesn’t matter if you call it with a domain that's already in ASCII.
+
+```js
+// encode domain names
+punycode.toASCII('mañana.com'); // 'xn--maana-pta.com'
+punycode.toASCII('☃-⌘.com'); // 'xn----dqo34k.com'
+```
+
+### `punycode.ucs2`
+
+#### `punycode.ucs2.decode(string)`
+
+Creates an array containing the numeric code point values of each Unicode symbol in the string. While [JavaScript uses UCS-2 internally](http://mathiasbynens.be/notes/javascript-encoding), this function will convert a pair of surrogate halves (each of which UCS-2 exposes as separate characters) into a single code point, matching UTF-16.
+
+```js
+punycode.ucs2.decode('abc'); // [0x61, 0x62, 0x63]
+// surrogate pair for U+1D306 TETRAGRAM FOR CENTRE:
+punycode.ucs2.decode('\uD834\uDF06'); // [0x1D306]
+```
+
+#### `punycode.ucs2.encode(codePoints)`
+
+Creates a string based on an array of numeric code point values.
+
+```js
+punycode.ucs2.encode([0x61, 0x62, 0x63]); // 'abc'
+punycode.ucs2.encode([0x1D306]); // '\uD834\uDF06'
+```
+
+### `punycode.version`
+
+A string representing the current Punycode.js version number.
+
+[Full API documentation is available.](https://github.com/bestiejs/punycode.js/tree/master/docs#readme)
+
+## Unit tests & code coverage
+
+After cloning this repository, run `npm install --dev` to install the dependencies needed for Punycode.js development and testing. You may want to install Istanbul _globally_ using `npm install istanbul -g`.
+
+Once that’s done, you can run the unit tests in Node using `npm test` or `node tests/tests.js`. To run the tests in Rhino, Ringo, Narwhal, PhantomJS, and web browsers as well, use `grunt test`.
+
+To generate [the code coverage report](http://rawgithub.com/bestiejs/punycode.js/master/coverage/punycode.js/punycode.js.html), use `grunt cover`.
+
+Feel free to fork if you see possible improvements!

It supports HTTPS and follows redirects by default.\n\n```javascript\nvar request = require('request');\nrequest('http://www.google.com', function (error, response, body) {\n  if (!error && response.statusCode == 200) {\n    console.log(body) // Print the google web page.\n  }\n})\n```\n\n## Streaming\n\nYou can stream any response to a file stream.\n\n```javascript\nrequest('http://google.com/doodle.png').pipe(fs.createWriteStream('doodle.png'))\n```\n\nYou can also stream a file to a PUT or POST request. This method will also check the file extension against a mapping of file extensions to content-types (in this case `application/json`) and use the proper `content-type` in the PUT request (if the headers don’t already provide one).\n\n```javascript\nfs.createReadStream('file.json').pipe(request.put('http://mysite.com/obj.json'))\n```\n\nRequest can also `pipe` to itself. When doing so, `content-type` and `content-length` are preserved in the PUT headers.\n\n```javascript\nrequest.get('http://google.com/img.png').pipe(request.put('http://mysite.com/img.png'))\n```\n\nNow let’s get fancy.\n\n```javascript\nhttp.createServer(function (req, resp) {\n  if (req.url === '/doodle.png') {\n    if (req.method === 'PUT') {\n      req.pipe(request.put('http://mysite.com/doodle.png'))\n    } else if (req.method === 'GET' || req.method === 'HEAD') {\n      request.get('http://mysite.com/doodle.png').pipe(resp)\n    }\n  }\n})\n```\n\nYou can also `pipe()` from `http.ServerRequest` instances, as well as to `http.ServerResponse` instances. The HTTP method, headers, and entity-body data will be sent. Which means that, if you don't really care about security, you can do:\n\n```javascript\nhttp.createServer(function (req, resp) {\n  if (req.url === '/doodle.png') {\n    var x = request('http://mysite.com/doodle.png')\n    req.pipe(x)\n    x.pipe(resp)\n  }\n})\n```\n\nAnd since `pipe()` returns the destination stream in ≥ Node 0.5.x you can do one line proxying. :)\n\n```javascript\nreq.pipe(request('http://mysite.com/doodle.png')).pipe(resp)\n```\n\nAlso, none of this new functionality conflicts with requests previous features, it just expands them.\n\n```javascript\nvar r = request.defaults({'proxy':'http://localproxy.com'})\n\nhttp.createServer(function (req, resp) {\n  if (req.url === '/doodle.png') {\n    r.get('http://google.com/doodle.png').pipe(resp)\n  }\n})\n```\n\nYou can still use intermediate proxies, the requests will still follow HTTP forwards, etc.\n\n## Forms\n\n`request` supports `application/x-www-form-urlencoded` and `multipart/form-data` form uploads. For `multipart/related` refer to the `multipart` API.\n\nURL-encoded forms are simple.\n\n```javascript\nrequest.post('http://service.com/upload', {form:{key:'value'}})\n// or\nrequest.post('http://service.com/upload').form({key:'value'})\n```\n\nFor `multipart/form-data` we use the [form-data](https://github.com/felixge/node-form-data) library by [@felixge](https://github.com/felixge). You don’t need to worry about piping the form object or setting the headers, `request` will handle that for you.\n\n```javascript\nvar r = request.post('http://service.com/upload')\nvar form = r.form()\nform.append('my_field', 'my_value')\nform.append('my_buffer', new Buffer([1, 2, 3]))\nform.append('my_file', fs.createReadStream(path.join(__dirname, 'doodle.png'))\nform.append('remote_file', request('http://google.com/doodle.png'))\n```\n\n## HTTP Authentication\n\n```javascript\nrequest.get('http://some.server.com/').auth('username', 'password', false);\n// or\nrequest.get('http://some.server.com/', {\n  'auth': {\n    'user': 'username',\n    'pass': 'password',\n    'sendImmediately': false\n  }\n});\n```\n\nIf passed as an option, `auth` should be a hash containing values `user` || `username`, `password` || `pass`, and `sendImmediately` (optional).  The method form takes parameters `auth(username, password, sendImmediately)`.\n\n`sendImmediately` defaults to `true`, which causes a basic authentication header to be sent.  If `sendImmediately` is `false`, then `request` will retry with a proper authentication header after receiving a `401` response from the server (which must contain a `WWW-Authenticate` header indicating the required authentication method).\n\nDigest authentication is supported, but it only works with `sendImmediately` set to `false`; otherwise `request` will send basic authentication on the initial request, which will probably cause the request to fail.\n\n## OAuth Signing\n\n```javascript\n// Twitter OAuth\nvar qs = require('querystring')\n  , oauth =\n    { callback: 'http://mysite.com/callback/'\n    , consumer_key: CONSUMER_KEY\n    , consumer_secret: CONSUMER_SECRET\n    }\n  , url = 'https://api.twitter.com/oauth/request_token'\n  ;\nrequest.post({url:url, oauth:oauth}, function (e, r, body) {\n  // Ideally, you would take the body in the response\n  // and construct a URL that a user clicks on (like a sign in button).\n  // The verifier is only available in the response after a user has\n  // verified with twitter that they are authorizing your app.\n  var access_token = qs.parse(body)\n    , oauth =\n      { consumer_key: CONSUMER_KEY\n      , consumer_secret: CONSUMER_SECRET\n      , token: access_token.oauth_token\n      , verifier: access_token.oauth_verifier\n      }\n    , url = 'https://api.twitter.com/oauth/access_token'\n    ;\n  request.post({url:url, oauth:oauth}, function (e, r, body) {\n    var perm_token = qs.parse(body)\n      , oauth =\n        { consumer_key: CONSUMER_KEY\n        , consumer_secret: CONSUMER_SECRET\n        , token: perm_token.oauth_token\n        , token_secret: perm_token.oauth_token_secret\n        }\n      , url = 'https://api.twitter.com/1.1/users/show.json?'\n      , params =\n        { screen_name: perm_token.screen_name\n        , user_id: perm_token.user_id\n        }\n      ;\n    url += qs.stringify(params)\n    request.get({url:url, oauth:oauth, json:true}, function (e, r, user) {\n      console.log(user)\n    })\n  })\n})\n```\n\n### Custom HTTP Headers\n\nHTTP Headers, such as `User-Agent`, can be set in the `options` object.\nIn the example below, we call the github API to find out the number\nof stars and forks for the request repository. This requires a\ncustom `User-Agent` header as well as https.\n\n```javascript\nvar request = require('request');\n\nvar options = {\n\turl: 'https://api.github.com/repos/mikeal/request',\n\theaders: {\n\t\t'User-Agent': 'request'\n\t}\n};\n\nfunction callback(error, response, body) {\n\tif (!error && response.statusCode == 200) {\n\t\tvar info = JSON.parse(body);\n\t\tconsole.log(info.stargazers_count + \" Stars\");\n\t\tconsole.log(info.forks_count + \" Forks\");\n\t}\n}\n\nrequest(options, callback);\n```\n\n### request(options, callback)\n\nThe first argument can be either a `url` or an `options` object. The only required option is `uri`; all others are optional.\n\n* `uri` || `url` - fully qualified uri or a parsed url object from `url.parse()`\n* `qs` - object containing querystring values to be appended to the `uri`\n* `method` - http method (default: `\"GET\"`)\n* `headers` - http headers (default: `{}`)\n* `body` - entity body for PATCH, POST and PUT requests. Must be a `Buffer` or `String`.\n* `form` - when passed an object, this sets `body` to a querystring representation of value, and adds `Content-type: application/x-www-form-urlencoded; charset=utf-8` header. When passed no options, a `FormData` instance is returned (and is piped to request).\n* `auth` - A hash containing values `user` || `username`, `password` || `pass`, and `sendImmediately` (optional).  See documentation above.\n* `json` - sets `body` but to JSON representation of value and adds `Content-type: application/json` header.  Additionally, parses the response body as JSON.\n* `multipart` - (experimental) array of objects which contains their own headers and `body` attribute. Sends `multipart/related` request. See example below.\n* `followRedirect` - follow HTTP 3xx responses as redirects (default: `true`)\n* `followAllRedirects` - follow non-GET HTTP 3xx responses as redirects (default: `false`)\n* `maxRedirects` - the maximum number of redirects to follow (default: `10`)\n* `encoding` - Encoding to be used on `setEncoding` of response data. If `null`, the `body` is returned as a `Buffer`.\n* `pool` - A hash object containing the agents for these requests. If omitted, the request will use the global pool (which is set to node's default `maxSockets`)\n* `pool.maxSockets` - Integer containing the maximum amount of sockets in the pool.\n* `timeout` - Integer containing the number of milliseconds to wait for a request to respond before aborting the request\n* `proxy` - An HTTP proxy to be used. Supports proxy Auth with Basic Auth, identical to support for the `url` parameter (by embedding the auth info in the `uri`)\n* `oauth` - Options for OAuth HMAC-SHA1 signing. See documentation above.\n* `hawk` - Options for [Hawk signing](https://github.com/hueniverse/hawk). The `credentials` key must contain the necessary signing info, [see hawk docs for details](https://github.com/hueniverse/hawk#usage-example).\n* `strictSSL` - If `true`, requires SSL certificates be valid. **Note:** to use your own certificate authority, you need to specify an agent that was created with that CA as an option.\n* `jar` - If `true`, remember cookies for future use (or define your custom cookie jar; see examples section)\n* `aws` - `object` containing AWS signing information. Should have the properties `key`, `secret`. Also requires the property `bucket`, unless you’re specifying your `bucket` as part of the path, or the request doesn’t use a bucket (i.e. GET Services)\n* `httpSignature` - Options for the [HTTP Signature Scheme](https://github.com/joyent/node-http-signature/blob/master/http_signing.md) using [Joyent's library](https://github.com/joyent/node-http-signature). The `keyId` and `key` properties must be specified. See the docs for other options.\n* `localAddress` - Local interface to bind for network connections.\n\n\nThe callback argument gets 3 arguments: \n\n1. An `error` when applicable (usually from [`http.ClientRequest`](http://nodejs.org/api/http.html#http_class_http_clientrequest) object)\n2. An [`http.IncomingMessage`](http://nodejs.org/api/http.html#http_http_incomingmessage) object\n3. The third is the `response` body (`String` or `Buffer`, or JSON object if the `json` option is supplied)\n\n## Convenience methods\n\nThere are also shorthand methods for different HTTP METHODs and some other conveniences.\n\n### request.defaults(options)\n\nThis method returns a wrapper around the normal request API that defaults to whatever options you pass in to it.\n\n### request.put\n\nSame as `request()`, but defaults to `method: \"PUT\"`.\n\n```javascript\nrequest.put(url)\n```\n\n### request.patch\n\nSame as `request()`, but defaults to `method: \"PATCH\"`.\n\n```javascript\nrequest.patch(url)\n```\n\n### request.post\n\nSame as `request()`, but defaults to `method: \"POST\"`.\n\n```javascript\nrequest.post(url)\n```\n\n### request.head\n\nSame as request() but defaults to `method: \"HEAD\"`.\n\n```javascript\nrequest.head(url)\n```\n\n### request.del\n\nSame as `request()`, but defaults to `method: \"DELETE\"`.\n\n```javascript\nrequest.del(url)\n```\n\n### request.get\n\nSame as `request()` (for uniformity).\n\n```javascript\nrequest.get(url)\n```\n### request.cookie\n\nFunction that creates a new cookie.\n\n```javascript\nrequest.cookie('cookie_string_here')\n```\n### request.jar\n\nFunction that creates a new cookie jar.\n\n```javascript\nrequest.jar()\n```\n\n\n## Examples:\n\n```javascript\n  var request = require('request')\n    , rand = Math.floor(Math.random()*100000000).toString()\n    ;\n  request(\n    { method: 'PUT'\n    , uri: 'http://mikeal.iriscouch.com/testjs/' + rand\n    , multipart:\n      [ { 'content-type': 'application/json'\n        ,  body: JSON.stringify({foo: 'bar', _attachments: {'message.txt': {follows: true, length: 18, 'content_type': 'text/plain' }}})\n        }\n      , { body: 'I am an attachment' }\n      ]\n    }\n  , function (error, response, body) {\n      if(response.statusCode == 201){\n        console.log('document saved as: http://mikeal.iriscouch.com/testjs/'+ rand)\n      } else {\n        console.log('error: '+ response.statusCode)\n        console.log(body)\n      }\n    }\n  )\n```\n\nCookies are disabled by default (else, they would be used in subsequent requests). To enable cookies, set `jar` to `true` (either in `defaults` or `options`).\n\n```javascript\nvar request = request.defaults({jar: true})\nrequest('http://www.google.com', function () {\n  request('http://images.google.com')\n})\n```\n\nTo use a custom cookie jar (instead `request`’s global cookie jar), set `jar` to an instance of `request.jar()` (either in `defaults` or `options`)\n\n```javascript\nvar j = request.jar()\nvar request = request.defaults({jar:j})\nrequest('http://www.google.com', function () {\n  request('http://images.google.com')\n})\n```\n\nOR\n\n```javascript\nvar j = request.jar()\nvar cookie = request.cookie('your_cookie_here')\nj.setCookie(cookie, uri);\nrequest({url: 'http://www.google.com', jar: j}, function () {\n  request('http://images.google.com')\n})\n```\n",
+  "readme": "# Request -- Simplified HTTP client\n\n[![NPM](https://nodei.co/npm/request.png)](https://nodei.co/npm/request/)\n\n## Super simple to use\n\nRequest is designed to be the simplest way possible to make http calls. It supports HTTPS and follows redirects by default.\n\n```javascript\nvar request = require('request');\nrequest('http://www.google.com', function (error, response, body) {\n  if (!error && response.statusCode == 200) {\n    console.log(body) // Print the google web page.\n  }\n})\n```\n\n## Streaming\n\nYou can stream any response to a file stream.\n\n```javascript\nrequest('http://google.com/doodle.png').pipe(fs.createWriteStream('doodle.png'))\n```\n\nYou can also stream a file to a PUT or POST request. This method will also check the file extension against a mapping of file extensions to content-types (in this case `application/json`) and use the proper `content-type` in the PUT request (if the headers don’t already provide one).\n\n```javascript\nfs.createReadStream('file.json').pipe(request.put('http://mysite.com/obj.json'))\n```\n\nRequest can also `pipe` to itself. When doing so, `content-type` and `content-length` are preserved in the PUT headers.\n\n```javascript\nrequest.get('http://google.com/img.png').pipe(request.put('http://mysite.com/img.png'))\n```\n\nNow let’s get fancy.\n\n```javascript\nhttp.createServer(function (req, resp) {\n  if (req.url === '/doodle.png') {\n    if (req.method === 'PUT') {\n      req.pipe(request.put('http://mysite.com/doodle.png'))\n    } else if (req.method === 'GET' || req.method === 'HEAD') {\n      request.get('http://mysite.com/doodle.png').pipe(resp)\n    }\n  }\n})\n```\n\nYou can also `pipe()` from `http.ServerRequest` instances, as well as to `http.ServerResponse` instances. The HTTP method, headers, and entity-body data will be sent. Which means that, if you don't really care about security, you can do:\n\n```javascript\nhttp.createServer(function (req, resp) {\n  if (req.url === '/doodle.png') {\n    var x = request('http://mysite.com/doodle.png')\n    req.pipe(x)\n    x.pipe(resp)\n  }\n})\n```\n\nAnd since `pipe()` returns the destination stream in ≥ Node 0.5.x you can do one line proxying. :)\n\n```javascript\nreq.pipe(request('http://mysite.com/doodle.png')).pipe(resp)\n```\n\nAlso, none of this new functionality conflicts with requests previous features, it just expands them.\n\n```javascript\nvar r = request.defaults({'proxy':'http://localproxy.com'})\n\nhttp.createServer(function (req, resp) {\n  if (req.url === '/doodle.png') {\n    r.get('http://google.com/doodle.png').pipe(resp)\n  }\n})\n```\n\nYou can still use intermediate proxies, the requests will still follow HTTP forwards, etc.\n\n## UNIX Socket \n\n`request` supports the `unix://` protocol for all requests. The path is assumed to be absolute to the root of the host file system. \n\nHTTP paths are extracted from the supplied URL by testing each level of the full URL against net.connect for a socket response.\n\nThus the following request will GET `/httppath` from the HTTP server listening on `/tmp/unix.socket`\n\n```javascript\nrequest.get('unix://tmp/unix.socket/httppath')\n```\n\n## Forms\n\n`request` supports `application/x-www-form-urlencoded` and `multipart/form-data` form uploads. For `multipart/related` refer to the `multipart` API.\n\nURL-encoded forms are simple.\n\n```javascript\nrequest.post('http://service.com/upload', {form:{key:'value'}})\n// or\nrequest.post('http://service.com/upload').form({key:'value'})\n```\n\nFor `multipart/form-data` we use the [form-data](https://github.com/felixge/node-form-data) library by [@felixge](https://github.com/felixge). You don’t need to worry about piping the form object or setting the headers, `request` will handle that for you.\n\n```javascript\nvar r = request.post('http://service.com/upload')\nvar form = r.form()\nform.append('my_field', 'my_value')\nform.append('my_buffer', new Buffer([1, 2, 3]))\nform.append('my_file', fs.createReadStream(path.join(__dirname, 'doodle.png'))\nform.append('remote_file', request('http://google.com/doodle.png'))\n```\n\n## HTTP Authentication\n\n```javascript\nrequest.get('http://some.server.com/').auth('username', 'password', false);\n// or\nrequest.get('http://some.server.com/', {\n  'auth': {\n    'user': 'username',\n    'pass': 'password',\n    'sendImmediately': false\n  }\n});\n```\n\nIf passed as an option, `auth` should be a hash containing values `user` || `username`, `password` || `pass`, and `sendImmediately` (optional).  The method form takes parameters `auth(username, password, sendImmediately)`.\n\n`sendImmediately` defaults to `true`, which causes a basic authentication header to be sent.  If `sendImmediately` is `false`, then `request` will retry with a proper authentication header after receiving a `401` response from the server (which must contain a `WWW-Authenticate` header indicating the required authentication method).\n\nDigest authentication is supported, but it only works with `sendImmediately` set to `false`; otherwise `request` will send basic authentication on the initial request, which will probably cause the request to fail.\n\n## OAuth Signing\n\n```javascript\n// Twitter OAuth\nvar qs = require('querystring')\n  , oauth =\n    { callback: 'http://mysite.com/callback/'\n    , consumer_key: CONSUMER_KEY\n    , consumer_secret: CONSUMER_SECRET\n    }\n  , url = 'https://api.twitter.com/oauth/request_token'\n  ;\nrequest.post({url:url, oauth:oauth}, function (e, r, body) {\n  // Ideally, you would take the body in the response\n  // and construct a URL that a user clicks on (like a sign in button).\n  // The verifier is only available in the response after a user has\n  // verified with twitter that they are authorizing your app.\n  var access_token = qs.parse(body)\n    , oauth =\n      { consumer_key: CONSUMER_KEY\n      , consumer_secret: CONSUMER_SECRET\n      , token: access_token.oauth_token\n      , verifier: access_token.oauth_verifier\n      }\n    , url = 'https://api.twitter.com/oauth/access_token'\n    ;\n  request.post({url:url, oauth:oauth}, function (e, r, body) {\n    var perm_token = qs.parse(body)\n      , oauth =\n        { consumer_key: CONSUMER_KEY\n        , consumer_secret: CONSUMER_SECRET\n        , token: perm_token.oauth_token\n        , token_secret: perm_token.oauth_token_secret\n        }\n      , url = 'https://api.twitter.com/1.1/users/show.json?'\n      , params =\n        { screen_name: perm_token.screen_name\n        , user_id: perm_token.user_id\n        }\n      ;\n    url += qs.stringify(params)\n    request.get({url:url, oauth:oauth, json:true}, function (e, r, user) {\n      console.log(user)\n    })\n  })\n})\n```\n\n### Custom HTTP Headers\n\nHTTP Headers, such as `User-Agent`, can be set in the `options` object.\nIn the example below, we call the github API to find out the number\nof stars and forks for the request repository. This requires a\ncustom `User-Agent` header as well as https.\n\n```javascript\nvar request = require('request');\n\nvar options = {\n\turl: 'https://api.github.com/repos/mikeal/request',\n\theaders: {\n\t\t'User-Agent': 'request'\n\t}\n};\n\nfunction callback(error, response, body) {\n\tif (!error && response.statusCode == 200) {\n\t\tvar info = JSON.parse(body);\n\t\tconsole.log(info.stargazers_count + \" Stars\");\n\t\tconsole.log(info.forks_count + \" Forks\");\n\t}\n}\n\nrequest(options, callback);\n```\n\n### request(options, callback)\n\nThe first argument can be either a `url` or an `options` object. The only required option is `uri`; all others are optional.\n\n* `uri` || `url` - fully qualified uri or a parsed url object from `url.parse()`\n* `qs` - object containing querystring values to be appended to the `uri`\n* `method` - http method (default: `\"GET\"`)\n* `headers` - http headers (default: `{}`)\n* `body` - entity body for PATCH, POST and PUT requests. Must be a `Buffer` or `String`.\n* `form` - when passed an object, this sets `body` to a querystring representation of value, and adds `Content-type: application/x-www-form-urlencoded; charset=utf-8` header. When passed no options, a `FormData` instance is returned (and is piped to request).\n* `auth` - A hash containing values `user` || `username`, `password` || `pass`, and `sendImmediately` (optional).  See documentation above.\n* `json` - sets `body` but to JSON representation of value and adds `Content-type: application/json` header.  Additionally, parses the response body as JSON.\n* `multipart` - (experimental) array of objects which contains their own headers and `body` attribute. Sends `multipart/related` request. See example below.\n* `followRedirect` - follow HTTP 3xx responses as redirects (default: `true`)\n* `followAllRedirects` - follow non-GET HTTP 3xx responses as redirects (default: `false`)\n* `maxRedirects` - the maximum number of redirects to follow (default: `10`)\n* `encoding` - Encoding to be used on `setEncoding` of response data. If `null`, the `body` is returned as a `Buffer`.\n* `pool` - A hash object containing the agents for these requests. If omitted, the request will use the global pool (which is set to node's default `maxSockets`)\n* `pool.maxSockets` - Integer containing the maximum amount of sockets in the pool.\n* `timeout` - Integer containing the number of milliseconds to wait for a request to respond before aborting the request\n* `proxy` - An HTTP proxy to be used. Supports proxy Auth with Basic Auth, identical to support for the `url` parameter (by embedding the auth info in the `uri`)\n* `oauth` - Options for OAuth HMAC-SHA1 signing. See documentation above.\n* `hawk` - Options for [Hawk signing](https://github.com/hueniverse/hawk). The `credentials` key must contain the necessary signing info, [see hawk docs for details](https://github.com/hueniverse/hawk#usage-example).\n* `strictSSL` - If `true`, requires SSL certificates be valid. **Note:** to use your own certificate authority, you need to specify an agent that was created with that CA as an option.\n* `jar` - If `true`, remember cookies for future use (or define your custom cookie jar; see examples section)\n* `aws` - `object` containing AWS signing information. Should have the properties `key`, `secret`. Also requires the property `bucket`, unless you’re specifying your `bucket` as part of the path, or the request doesn’t use a bucket (i.e. GET Services)\n* `httpSignature` - Options for the [HTTP Signature Scheme](https://github.com/joyent/node-http-signature/blob/master/http_signing.md) using [Joyent's library](https://github.com/joyent/node-http-signature). The `keyId` and `key` properties must be specified. See the docs for other options.\n* `localAddress` - Local interface to bind for network connections.\n\n\nThe callback argument gets 3 arguments: \n\n1. An `error` when applicable (usually from [`http.ClientRequest`](http://nodejs.org/api/http.html#http_class_http_clientrequest) object)\n2. An [`http.IncomingMessage`](http://nodejs.org/api/http.html#http_http_incomingmessage) object\n3. The third is the `response` body (`String` or `Buffer`, or JSON object if the `json` option is supplied)\n\n## Convenience methods\n\nThere are also shorthand methods for different HTTP METHODs and some other conveniences.\n\n### request.defaults(options)\n\nThis method returns a wrapper around the normal request API that defaults to whatever options you pass in to it.\n\n### request.put\n\nSame as `request()`, but defaults to `method: \"PUT\"`.\n\n```javascript\nrequest.put(url)\n```\n\n### request.patch\n\nSame as `request()`, but defaults to `method: \"PATCH\"`.\n\n```javascript\nrequest.patch(url)\n```\n\n### request.post\n\nSame as `request()`, but defaults to `method: \"POST\"`.\n\n```javascript\nrequest.post(url)\n```\n\n### request.head\n\nSame as request() but defaults to `method: \"HEAD\"`.\n\n```javascript\nrequest.head(url)\n```\n\n### request.del\n\nSame as `request()`, but defaults to `method: \"DELETE\"`.\n\n```javascript\nrequest.del(url)\n```\n\n### request.get\n\nSame as `request()` (for uniformity).\n\n```javascript\nrequest.get(url)\n```\n### request.cookie\n\nFunction that creates a new cookie.\n\n```javascript\nrequest.cookie('cookie_string_here')\n```\n### request.jar\n\nFunction that creates a new cookie jar.\n\n```javascript\nrequest.jar()\n```\n\n\n## Examples:\n\n```javascript\n  var request = require('request')\n    , rand = Math.floor(Math.random()*100000000).toString()\n    ;\n  request(\n    { method: 'PUT'\n    , uri: 'http://mikeal.iriscouch.com/testjs/' + rand\n    , multipart:\n      [ { 'content-type': 'application/json'\n        ,  body: JSON.stringify({foo: 'bar', _attachments: {'message.txt': {follows: true, length: 18, 'content_type': 'text/plain' }}})\n        }\n      , { body: 'I am an attachment' }\n      ]\n    }\n  , function (error, response, body) {\n      if(response.statusCode == 201){\n        console.log('document saved as: http://mikeal.iriscouch.com/testjs/'+ rand)\n      } else {\n        console.log('error: '+ response.statusCode)\n        console.log(body)\n      }\n    }\n  )\n```\n\nCookies are disabled by default (else, they would be used in subsequent requests).

The walking function is called for each\nsource file content and is passed the filename and source content.\n\n* `fn`: The traversal function.\n\n#### SourceNode.prototype.join(sep)\n\nLike `Array.prototype.join` except for SourceNodes. Inserts the separator\nbetween each of this source node's children.\n\n* `sep`: The separator.\n\n#### SourceNode.prototype.replaceRight(pattern, replacement)\n\nCall `String.prototype.replace` on the very right-most source snippet.

You have\naccess to the following assertion functions:\n\n* `doesNotThrow`\n\n* `equal`\n\n* `ok`\n\n* `strictEqual`\n\n* `throws`\n\n(The reason for the restricted set of test functions is because we need the\ntests to run inside Firefox's test suite as well and so the assert module is\nshimmed in that environment. See `build/assert-shim.js`.)\n\n[format]: https://docs.google.com/document/d/1U1RGAehQwRypUTovF1KRlpiOFze0b-_2gc6fAH0KY0k/edit\n[feature]: https://wiki.mozilla.org/DevTools/Features/SourceMap\n[Dryice]: https://github.com/mozilla/dryice\n",

Walks over the tree and\nconcatenates all the various snippets together to one string.\n\n### SourceNode.prototype.toStringWithSourceMap([startOfSourceMap])\n\nReturns the string representation of this tree of source nodes, plus a\nSourceMapGenerator which contains all the mappings between the generated and\noriginal sources.\n\nThe arguments are the same as those to `new SourceMapGenerator`.\n\n## Tests\n\n[![Build Status](https://travis-ci.org/mozilla/source-map.png?branch=master)](https://travis-ci.org/mozilla/source-map)\n\nInstall NodeJS version 0.8.0 or greater, then run `node test/run-tests.js`.\n\nTo add new tests, create a new file named `test/test-<your new test name>.js`\nand export your test functions with names that start with \"test\", for example\n\n    exports[\"test doing the foo bar\"] = function (assert, util) {\n      ...\n    };\n\nThe new test will be located automatically when you run the suite.\n\nThe `util` argument is the test utility module located at `test/source-map/util`.\n\nThe `assert` argument is a cut down version of node's assert module. You have\naccess to the following assertion functions:\n\n* `doesNotThrow`\n\n* `equal`\n\n* `ok`\n\n* `strictEqual`\n\n* `throws`\n\n(The reason for the restricted set of test functions is because we need the\ntests to run inside Firefox's test suite as well and so the assert module is\nshimmed in that environment. See `build/assert-shim.js`.)\n\n[format]: https://docs.google.com/document/d/1U1RGAehQwRypUTovF1KRlpiOFze0b-_2gc6fAH0KY0k/edit\n[feature]: https://wiki.mozilla.org/DevTools/Features/SourceMap\n[Dryice]: https://github.com/mozilla/dryice\n",

[http://lesscss.org](http://lesscss.org).\r\n\r\nThis is the JavaScript, and now official, stable version of LESS.\r\n\r\n\r\n## Getting Started\r\n\r\nOptions for adding Less.js to your project:\r\n\r\n* Install with [NPM](https://npmjs.org/): `npm install less`\r\n* [Download the latest release][download]\r\n* Clone the repo: `git clone git://github.com/less/less.js.git`\r\n\r\n\r\n\r\n## Feature Highlights\r\nLESS extends CSS with dynamic features such as:\r\n\r\n* [nesting](#nesting)\r\n* [variables](#variables)\r\n* [operations](#operations)\r\n* [mixins](#mixins)\r\n* [extend](#extend) (selector inheritance)\r\n\r\nTo learn about the many other features Less.js has to offer please visit [http://lesscss.org](http://lesscss.org) and [the Less.js wiki][wiki]\r\n\r\n\r\n### Examples\r\n#### nesting\r\nTake advantage of nesting to make code more readable and maintainable. This:\r\n\r\n```less\r\n.nav > li > a {\r\n  border: 1px solid #f5f5f5;\r\n  &:hover {\r\n    border-color: #ddd;\r\n  }\r\n}\r\n```\r\n\r\nrenders to:\r\n\r\n```css\r\n.nav > li > a {\r\n  border: 1px solid #f5f5f5;\r\n}\r\n.nav > li > a:hover {\r\n  border-color: #ddd;\r\n}\r\n```\r\n\r\n\r\n#### variables\r\nUpdated commonly used values from a single location.\r\n\r\n```less\r\n// Variables (\"inline\" comments like this can be used)\r\n@link-color:  #428bca; // appears as \"sea blue\"\r\n\r\n/* Or \"block comments\" that span\r\n   multiple lines, like this */\r\na {\r\n  color: @link-color; // use the variable in styles\r\n}\r\n```\r\n\r\nVariables can also be used in `@import` statements, URLs, selector names, and more.\r\n\r\n\r\n\r\n#### operations\r\nContinuing with the same example above, we can use our variables even easier to maintain with _operations_, which enables the use of addition, subraction, multiplication and division in your styles:\r\n\r\n```less\r\n// Variables\r\n@link-color:        #428bca;\r\n@link-color-hover:  darken(@link-color, 10%);\r\n\r\n// Styles\r\na {\r\n  color: @link-color;\r\n}\r\na:hover {\r\n  color: @link-color-hover;\r\n}\r\n```\r\nrenders to:\r\n\r\n```css\r\na {\r\n  color: #428bca;\r\n}\r\na:hover {\r\n  color: #3071a9;\r\n}\r\n```\r\n\r\n#### mixins\r\n##### \"implicit\" mixins\r\nMixins enable you to apply the styles of one selector inside another selector like this:\r\n\r\n```less\r\n// Variables\r\n@link-color:        #428bca;\r\n\r\n// Any \"regular\" class...\r\n.link {\r\n  color: @link-color;\r\n}\r\na {\r\n  font-weight: bold;\r\n  .link; // ...can be used as an \"implicit\" mixin\r\n}\r\n```\r\n\r\nrenders to:\r\n\r\n```css\r\n.link {\r\n  color: #428bca;\r\n}\r\na {\r\n  font-weight: bold;\r\n  color: #428bca;\r\n}\r\n```\r\n\r\nSo any selector can be an \"implicit mixin\". We'll show you a DRYer way to do this below.\r\n\r\n\r\n\r\n##### parametric mixins\r\nMixins can also accept parameters:\r\n\r\n```less\r\n// Transition mixin\r\n.transition(@transition) {\r\n  -webkit-transition: @transition;\r\n     -moz-transition: @transition;\r\n       -o-transition: @transition;\r\n          transition: @transition;\r\n}\r\n```\r\n\r\nused like this:\r\n\r\n```less\r\n// Variables\r\n@link-color:        #428bca;\r\n@link-color-hover:  darken(@link-color, 10%);\r\n\r\n//Transition mixin would be anywhere here\r\n\r\na {\r\n  font-weight: bold;\r\n  color: @link-color;\r\n  .transition(color .2s ease-in-out);\r\n  // Hover state\r\n  &:hover {\r\n    color: @link-color-hover;\r\n  }\r\n}\r\n```\r\n\r\nrenders to:\r\n\r\n```css\r\na {\r\n  font-weight: bold;\r\n  color: #428bca;\r\n  -webkit-transition: color 0.2s ease-in-out;\r\n     -moz-transition: color 0.2s ease-in-out;\r\n       -o-transition: color 0.2s ease-in-out;\r\n          transition: color 0.2s ease-in-out;\r\n}\r\na:hover {\r\n  color: #3071a9;\r\n}\r\n```\r\n\r\n\r\n#### extend\r\nThe `extend` feature can be thought of as the _inverse_ of mixins. It accomplishes the goal of \"borrowing styles\", but rather than copying all the rules of _Selector A_ over to _Selector B_, `extend` copies the name of the _inheriting selector_ (_Selector B_) over to the _extending selector_ (_Selector A_). So continuing with the example used for [mixins](#mixins) above, extend works like this:\r\n\r\n```less\r\n// Variables\r\n@link-color:        #428bca;\r\n\r\n.link {\r\n  color: @link-color;\r\n}\r\na:extend(.link) {\r\n  font-weight: bold;\r\n}\r\n// Can also be written as\r\na {\r\n  &:extend(.link);\r\n  font-weight: bold;\r\n}\r\n```\r\n\r\nrenders to:\r\n\r\n```css\r\n.link, a {\r\n  color: #428bca;\r\n}\r\na {\r\n  font-weight: bold;\r\n}\r\n```\r\n\r\n## Usage\r\n\r\n### Compiling and Parsing\r\nInvoke the compiler from node:\r\n\r\n```javascript\r\nvar less = require('less');\r\n\r\nless.render('.class { width: (1 + 1) }', function (e, css) {\r\n    console.log(css);\r\n});\r\n```\r\n\r\nOutputs:\r\n\r\n```css\r\n.class {\r\n  width: 2;\r\n}\r\n```\r\n\r\nYou may also manually invoke the parser and compiler:\r\n\r\n```javascript\r\nvar parser = new(less.Parser);\r\n\r\nparser.parse('.class { width: (1 + 1) }', function (err, tree) {\r\n    if (err) { return console.error(err) }\r\n    console.log(tree.toCSS());\r\n});\r\n```\r\n\r\n\r\n### Configuration\r\nYou may also pass options to the compiler:\r\n\r\n```javascript\r\nvar parser = new(less.Parser)({\r\n    paths: ['.', './src/less'], // Specify search paths for @import directives\r\n    filename: 'style.less'      // Specify a filename, for better error messages\r\n});\r\n\r\nparser.parse('.class { width: (1 + 1) }', function (e, tree) {\r\n    tree.toCSS({ compress: true }); // Minify CSS output\r\n});\r\n```\r\n\r\n## More information\r\n\r\nFor general information on the language, configuration options or usage visit [lesscss.org](http://lesscss.org) or [the less wiki][wiki].\r\n\r\nHere are other resources for using Less.js:\r\n\r\n* [stackoverflow.com][so] is a great place to get answers about Less.\r\n* [node.js tools](https://github.com/less/less.js/wiki/Converting-LESS-to-CSS) for converting Less to CSS\r\n* [GUI compilers for Less](https://github.com/less/less.js/wiki/GUI-compilers-that-use-LESS.js)\r\n* [Less.js Issues][issues] for reporting bugs\r\n\r\n\r\n\r\n## Contributing\r\nPlease read [CONTRIBUTING.md](./CONTRIBUTING.md). Add unit tests for any new or changed functionality. Lint and test your code using [Grunt](http://gruntjs.com/).\r\n\r\n### Reporting Issues\r\n\r\nBefore opening any issue, please search for existing issues and read the [Issue Guidelines](https://github.com/necolas/issue-guidelines), written by [Nicolas Gallagher](https://github.com/necolas/). After that if you find a bug or would like to make feature request, [please open a new issue][issues].\r\n\r\nPlease report documentation issues in [the documentation project](https://github.com/less/less-docs).\r\n\r\n### Development\r\n\r\n#### Install Less.js\r\n\r\nStart by either [downloading this project][download] manually, or in the command line:\r\n\r\n```shell\r\ngit clone https://github.com/less/less.js.git \"less\"\r\n```\r\nand then `cd less`.\r\n\r\n\r\n#### Install dependencies\r\n\r\nTo install all the dependencies for less development, run:\r\n\r\n```shell\r\nnpm install\r\n```\r\n\r\nIf you haven't run grunt before, install grunt-cli globally so you can just run `grunt`\r\n\r\n```shell\r\nnpm install grunt-cli -g\r\n```\r\n\r\nYou should now be able to build Less.js, run tests, benchmarking, and other tasks listed in the Gruntfile.\r\n\r\n## Using Less.js Grunt\r\n\r\nTests, benchmarking and building is done using Grunt `~0.4.1`. If you haven't used [Grunt](http://gruntjs.com/) before, be sure to check out the [Getting Started](http://gruntjs.com/getting-started) guide, as it explains how to install and use Grunt plugins, which are necessary for development with Less.js.\r\n\r\nThe Less.js [Gruntfile](Gruntfile.js) is configured with the following \"convenience tasks\" :\r\n\r\n#### test - `grunt`\r\nRuns jshint, nodeunit and headless jasmine tests using [phantomjs](http://code.google.com/p/phantomjs/). You must have phantomjs installed for the jasmine tests to run.\r\n\r\n#### test - `grunt benchmark`\r\nRuns the benchmark suite.\r\n\r\n#### build for testing browser - 'grunt browser'\r\nThis builds less.js and puts it in 'test/browser/less.js'\r\n\r\n#### build - `grunt stable | grunt beta | grunt alpha`\r\nBuilds Less.js from from the `/lib/less` source files. This is done by the developer releasing a new release, do not do this if you are creating a pull request.\r\n\r\n#### readme - `grunt readme`\r\nBuild the README file from [a template](build/README.md) to ensure that metadata is up-to-date and (more likely to be) correct.\r\n\r\nPlease review the [Gruntfile](Gruntfile.js) to become acquainted with the other available tasks.\r\n\r\n**Please note** that if you have any issues installing dependencies or running any of the Gruntfile commands, please make sure to uninstall any previous versions, both in the local node_modules directory, and clear your global npm cache, and then try running `npm install` again. After that if you still have issues, please let us know about it so we can help.\r\n\r\n\r\n## Release History\r\nSee the [changelog](CHANGELOG.md)\r\n\r\n## [License](LICENSE)\r\n\r\nCopyright (c) 2009-2014 [Alexis Sellier](http://cloudhead.io/) & The Core Less Team\r\nLicensed under the [Apache License](LICENSE).\r\n\r\n\r\n[so]: http://stackoverflow.com/questions/tagged/twitter-bootstrap+less \"StackOverflow.com\"\r\n[issues]: https://github.com/less/less.js/issues \"GitHub Issues for Less.js\"\r\n[wiki]: https://github.com/less/less.js/wiki \"The official wiki for Less.js\"\r\n[download]: https://github.com/less/less.js/zipball/master \"Download Less.js\"",

 # readable-stream
 
-A new class of streams for Node.js
+***Node-core streams for userland***
 
-This module provides the new Stream base classes introduced in Node
-v0.10, for use in Node v0.8.  You can use it to have programs that
-have to work with node v0.8, while being forward-compatible for v0.10
-and beyond.  When you drop support for v0.8, you can remove this
-module, and only use the native streams.
+[![NPM](https://nodei.co/npm/readable-stream.png?downloads=true)](https://nodei.co/npm/readable-stream/)
+[![NPM](https://nodei.co/npm-dl/readable-stream.png)](https://nodei.co/npm/readable-stream/)
 
-This is almost exactly the same codebase as appears in Node v0.10.
-However:
+This package is a mirror of the Streams2 and Streams3 implementations in Node-core.
 
-1. The exported object is actually the Readable class.  Decorating the
-   native `stream` module would be global pollution.
-2. In v0.10, you can safely use `base64` as an argument to
-   `setEncoding` in Readable streams.  However, in v0.8, the
-   StringDecoder class has no `end()` method, which is problematic for
-   Base64.  So, don't use that, because it'll break and be weird.
+If you want to guarantee a stable streams base, regardless of what version of Node you, or the users of your libraries are using, use **readable-stream** *only* and avoid the *"stream"* module in Node-core.
 
-Other than that, the API is the same as `require('stream')` in v0.10,
-so the API docs are reproduced below.
+**readable-stream** comes in two major versions, v1.0.x and v1.1.x. The former tracks the Streams2 implementation in Node 0.10, including bug-fixes and minor improvements as they are added. The latter tracks Streams3 as it develops in Node 0.11; we will likely see a v1.2.x branch for Node 0.12.
 
-----------
+**readable-stream** uses proper patch-level versioning so if you pin to `"~1.0.0"` you’ll get the latest Node 0.10 Streams2 implementation, including any fixes and minor non-breaking improvements. The patch-level versions of 1.0.x and 1.1.x should mirror the patch-level versions of Node-core releases. You should prefer the **1.0.x** releases for now and when you’re ready to start using Streams3, pin to `"~1.1.0"`
 
-    Stability: 2 - Unstable
-
-A stream is an abstract interface implemented by various objects in
-Node.  For example a request to an HTTP server is a stream, as is
-stdout. Streams are readable, writable, or both. All streams are
-instances of [EventEmitter][]
-
-You can load the Stream base classes by doing `require('stream')`.
-There are base classes provided for Readable streams, Writable
-streams, Duplex streams, and Transform streams.
-
-## Compatibility
-
-In earlier versions of Node, the Readable stream interface was
-simpler, but also less powerful and less useful.
-
-* Rather than waiting for you to call the `read()` method, `'data'`
-  events would start emitting immediately.  If you needed to do some
-  I/O to decide how to handle data, then you had to store the chunks
-  in some kind of buffer so that they would not be lost.
-* The `pause()` method was advisory, rather than guaranteed.  This
-  meant that you still had to be prepared to receive `'data'` events
-  even when the stream was in a paused state.
-
-In Node v0.10, the Readable class described below was added.  For
-backwards compatibility with older Node programs, Readable streams
-switch into "old mode" when a `'data'` event handler is added, or when
-the `pause()` or `resume()` methods are called.  The effect is that,
-even if you are not using the new `read()` method and `'readable'`
-event, you no longer have to worry about losing `'data'` chunks.
-
-Most programs will continue to function normally.  However, this
-introduces an edge case in the following conditions:
-
-* No `'data'` event handler is added.
-* The `pause()` and `resume()` methods are never called.
-
-For example, consider the following code:
-
-```javascript
-// WARNING!  BROKEN!
-net.createServer(function(socket) {
-
-  // we add an 'end' method, but never consume the data
-  socket.on('end', function() {
-    // It will never get here.
-    socket.end('I got your message (but didnt read it)\n');
-  });
-
-}).listen(1337);
-```
-
-In versions of node prior to v0.10, the incoming message data would be
-simply discarded.  However, in Node v0.10 and beyond, the socket will
-remain paused forever.
-
-The workaround in this situation is to call the `resume()` method to
-trigger "old mode" behavior:
-
-```javascript
-// Workaround
-net.createServer(function(socket) {
-
-  socket.on('end', function() {
-    socket.end('I got your message (but didnt read it)\n');
-  });
-
-  // start the flow of data, discarding it.
-  socket.resume();
-
-}).listen(1337);
-```
-
-In addition to new Readable streams switching into old-mode, pre-v0.10
-style streams can be wrapped in a Readable class using the `wrap()`
-method.
-
-## Class: stream.Readable
-
-<!--type=class-->
-
-A `Readable Stream` has the following methods, members, and events.
-
-Note that `stream.Readable` is an abstract class designed to be
-extended with an underlying implementation of the `_read(size)`
-method. (See below.)
-
-### new stream.Readable([options])
-
-* `options` {Object}
-  * `highWaterMark` {Number} The maximum number of bytes to store in
-    the internal buffer before ceasing to read from the underlying
-    resource.  Default=16kb
-  * `encoding` {String} If specified, then buffers will be decoded to
-    strings using the specified encoding.  Default=null
-  * `objectMode` {Boolean} Whether this stream should behave
-    as a stream of objects. Meaning that stream.read(n) returns
-    a single value instead of a Buffer of size n
-
-In classes that extend the Readable class, make sure to call the
-constructor so that the buffering settings can be properly
-initialized.
-
-### readable.\_read(size)
-
-* `size` {Number} Number of bytes to read asynchronously
-
-Note: **This function should NOT be called directly.**  It should be
-implemented by child classes, and called by the internal Readable
-class methods only.
-
-All Readable stream implementations must provide a `_read` method
-to fetch data from the underlying resource.
-
-This method is prefixed with an underscore because it is internal to
-the class that defines it, and should not be called directly by user
-programs.  However, you **are** expected to override this method in
-your own extension classes.
-
-When data is available, put it into the read queue by calling
-`readable.push(chunk)`.  If `push` returns false, then you should stop
-reading.  When `_read` is called again, you should start pushing more
-data.
-
-The `size` argument is advisory.  Implementations where a "read" is a
-single call that returns data can use this to know how much data to
-fetch.  Implementations where that is not relevant, such as TCP or
-TLS, may ignore this argument, and simply provide data whenever it
-becomes available.  There is no need, for example to "wait" until
-`size` bytes are available before calling `stream.push(chunk)`.
-
-### readable.push(chunk)
-
-* `chunk` {Buffer | null | String} Chunk of data to push into the read queue
-* return {Boolean} Whether or not more pushes should be performed
-
-Note: **This function should be called by Readable implementors, NOT
-by consumers of Readable subclasses.**  The `_read()` function will not
-be called again until at least one `push(chunk)` call is made.  If no
-data is available, then you MAY call `push('')` (an empty string) to
-allow a future `_read` call, without adding any data to the queue.
-
-The `Readable` class works by putting data into a read queue to be
-pulled out later by calling the `read()` method when the `'readable'`
-event fires.
-
-The `push()` method will explicitly insert some data into the read
-queue.  If it is called with `null` then it will signal the end of the
-data.
-
-In some cases, you may be wrapping a lower-level source which has some
-sort of pause/resume mechanism, and a data callback.  In those cases,
-you could wrap the low-level source object by doing something like
-this:
-
-```javascript
-// source is an object with readStop() and readStart() methods,
-// and an `ondata` member that gets called when it has data, and
-// an `onend` member that gets called when the data is over.
-
-var stream = new Readable();
-
-source.ondata = function(chunk) {
-  // if push() returns false, then we need to stop reading from source
-  if (!stream.push(chunk))
-    source.readStop();
-};
-
-source.onend = function() {
-  stream.push(null);
-};
-
-// _read will be called when the stream wants to pull more data in
-// the advisory size argument is ignored in this case.
-stream._read = function(n) {
-  source.readStart();
-};
-```
-
-### readable.unshift(chunk)
-
-* `chunk` {Buffer | null | String} Chunk of data to unshift onto the read queue
-* return {Boolean} Whether or not more pushes should be performed
-
-This is the corollary of `readable.push(chunk)`.  Rather than putting
-the data at the *end* of the read queue, it puts it at the *front* of
-the read queue.
-
-This is useful in certain use-cases where a stream is being consumed
-by a parser, which needs to "un-consume" some data that it has
-optimistically pulled out of the source.
-
-```javascript
-// A parser for a simple data protocol.
-// The "header" is a JSON object, followed by 2 \n characters, and
-// then a message body.
-//
-// Note: This can be done more simply as a Transform stream.  See below.
-
-function SimpleProtocol(source, options) {
-  if (!(this instanceof SimpleProtocol))
-    return new SimpleProtocol(options);
-
-  Readable.call(this, options);
-  this._inBody = false;
-  this._sawFirstCr = false;
-
-  // source is a readable stream, such as a socket or file
-  this._source = source;
-
-  var self = this;
-  source.on('end', function() {
-    self.push(null);
-  });
-
-  // give it a kick whenever the source is readable
-  // read(0) will not consume any bytes
-  source.on('readable', function() {
-    self.read(0);
-  });
-
-  this._rawHeader = [];

-    if (chunk === null)
-      return this.push('');
-
-    // check if the chunk has a \n\n
-    var split = -1;
-    for (var i = 0; i < chunk.length; i++) {
-      if (chunk[i] === 10) { // '\n'
-        if (this._sawFirstCr) {
-          split = i;
-          break;
-        } else {
-          this._sawFirstCr = true;
-        }
-      } else {
-        this._sawFirstCr = false;
-      }
-    }
-
-    if (split === -1) {
-      // still waiting for the \n\n
-      // stash the chunk, and try again.
-      this._rawHeader.push(chunk);
-      this.push('');
-    } else {
-      this._inBody = true;
-      var h = chunk.slice(0, split);
-      this._rawHeader.push(h);
-      var header = Buffer.concat(this._rawHeader).toString();
-      try {
-        this.header = JSON.parse(header);
-      } catch (er) {
-        this.emit('error', new Error('invalid simple protocol data'));
-        return;
-      }
-      // now, because we got some extra data, unshift the rest
-      // back into the read queue so that our consumer will see it.
-      var b = chunk.slice(split);
-      this.unshift(b);
-
-      // and let them know that we are done parsing the header.
-      this.emit('header', this.header);
-    }
-  } else {
-    // from there on, just provide the data to our consumer.
-    // careful not to push(null), since that would indicate EOF.
-    var chunk = this._source.read();
-    if (chunk) this.push(chunk);
-  }
-};
-
-// Usage:
-var parser = new SimpleProtocol(source);
-// Now parser is a readable stream that will emit 'header'
-// with the parsed header data.
-```
-
-### readable.wrap(stream)
-
-* `stream` {Stream} An "old style" readable stream
-
-If you are using an older Node library that emits `'data'` events and
-has a `pause()` method that is advisory only, then you can use the
-`wrap()` method to create a Readable stream that uses the old stream
-as its data source.
-
-For example:
-
-```javascript
-var OldReader = require('./old-api-module.js').OldReader;
-var oreader = new OldReader;
-var Readable = require('stream').Readable;
-var myReader = new Readable().wrap(oreader);
-
-myReader.on('readable', function() {
-  myReader.read(); // etc.
-});
-```
-
-### Event: 'readable'
-
-When there is data ready to be consumed, this event will fire.
-
-When this event emits, call the `read()` method to consume the data.
-
-### Event: 'end'
-
-Emitted when the stream has received an EOF (FIN in TCP terminology).
-Indicates that no more `'data'` events will happen. If the stream is
-also writable, it may be possible to continue writing.
-
-### Event: 'data'
-
-The `'data'` event emits either a `Buffer` (by default) or a string if
-`setEncoding()` was used.
-
-Note that adding a `'data'` event listener will switch the Readable
-stream into "old mode", where data is emitted as soon as it is
-available, rather than waiting for you to call `read()` to consume it.
-
-### Event: 'error'
-
-Emitted if there was an error receiving data.
-
-### Event: 'close'
-
-Emitted when the underlying resource (for example, the backing file
-descriptor) has been closed. Not all streams will emit this.
-
-### readable.setEncoding(encoding)
-
-Makes the `'data'` event emit a string instead of a `Buffer`. `encoding`
-can be `'utf8'`, `'utf16le'` (`'ucs2'`), `'ascii'`, or `'hex'`.
-
-The encoding can also be set by specifying an `encoding` field to the
-constructor.
-
-### readable.read([size])
-
-* `size` {Number | null} Optional number of bytes to read.
-* Return: {Buffer | String | null}
-
-Note: **This function SHOULD be called by Readable stream users.**
-
-Call this method to consume data once the `'readable'` event is
-emitted.
-
-The `size` argument will set a minimum number of bytes that you are
-interested in.  If not set, then the entire content of the internal
-buffer is returned.
-
-If there is no data to consume, or if there are fewer bytes in the
-internal buffer than the `size` argument, then `null` is returned, and
-a future `'readable'` event will be emitted when more is available.
-
-Calling `stream.read(0)` will always return `null`, and will trigger a
-refresh of the internal buffer, but otherwise be a no-op.
-
-### readable.pipe(destination, [options])
-
-* `destination` {Writable Stream}
-* `options` {Object} Optional
-  * `end` {Boolean} Default=true
-
-Connects this readable stream to `destination` WriteStream. Incoming
-data on this stream gets written to `destination`.  Properly manages
-back-pressure so that a slow destination will not be overwhelmed by a
-fast readable stream.
-
-This function returns the `destination` stream.
-
-For example, emulating the Unix `cat` command:
-
-    process.stdin.pipe(process.stdout);
-
-By default `end()` is called on the destination when the source stream
-emits `end`, so that `destination` is no longer writable. Pass `{ end:
-false }` as `options` to keep the destination stream open.
-
-This keeps `writer` open so that "Goodbye" can be written at the
-end.
-
-    reader.pipe(writer, { end: false });
-    reader.on("end", function() {
-      writer.end("Goodbye\n");
-    });
-
-Note that `process.stderr` and `process.stdout` are never closed until
-the process exits, regardless of the specified options.
-
-### readable.unpipe([destination])
-
-* `destination` {Writable Stream} Optional
-
-Undo a previously established `pipe()`.  If no destination is
-provided, then all previously established pipes are removed.
-
-### readable.pause()
-
-Switches the readable stream into "old mode", where data is emitted
-using a `'data'` event rather than being buffered for consumption via
-the `read()` method.
-
-Ceases the flow of data.  No `'data'` events are emitted while the
-stream is in a paused state.
-
-### readable.resume()
-
-Switches the readable stream into "old mode", where data is emitted
-using a `'data'` event rather than being buffered for consumption via
-the `read()` method.
-
-Resumes the incoming `'data'` events after a `pause()`.
-
-
-## Class: stream.Writable
-
-<!--type=class-->
-
-A `Writable` Stream has the following methods, members, and events.
-
-Note that `stream.Writable` is an abstract class designed to be
-extended with an underlying implementation of the
-`_write(chunk, encoding, cb)` method. (See below.)
-
-### new stream.Writable([options])
-
-* `options` {Object}
-  * `highWaterMark` {Number} Buffer level when `write()` starts
-    returning false. Default=16kb
-  * `decodeStrings` {Boolean} Whether or not to decode strings into
-    Buffers before passing them to `_write()`.  Default=true
-
-In classes that extend the Writable class, make sure to call the
-constructor so that the buffering settings can be properly
-initialized.
-
-### writable.\_write(chunk, encoding, callback)
-
-* `chunk` {Buffer | String} The chunk to be written.  Will always
-  be a buffer unless the `decodeStrings` option was set to `false`.
-* `encoding` {String} If the chunk is a string, then this is the
-  encoding type.  Ignore chunk is a buffer.  Note that chunk will
-  **always** be a buffer unless the `decodeStrings` option is
-  explicitly set to `false`.
-* `callback` {Function} Call this function (optionally with an error
-  argument) when you are done processing the supplied chunk.
-
-All Writable stream implementations must provide a `_write` method to
-send data to the underlying resource.
-
-Note: **This function MUST NOT be called directly.**  It should be
-implemented by child classes, and called by the internal Writable
-class methods only.
-
-Call the callback using the standard `callback(error)` pattern to
-signal that the write completed successfully or with an error.
-
-If the `decodeStrings` flag is set in the constructor options, then
-`chunk` may be a string rather than a Buffer, and `encoding` will
-indicate the sort of string that it is.  This is to support
-implementations that have an optimized handling for certain string
-data encodings.  If you do not explicitly set the `decodeStrings`
-option to `false`, then you can safely ignore the `encoding` argument,
-and assume that `chunk` will always be a Buffer.
-
-This method is prefixed with an underscore because it is internal to
-the class that defines it, and should not be called directly by user
-programs.  However, you **are** expected to override this method in
-your own extension classes.
-
-
-### writable.write(chunk, [encoding], [callback])
-
-* `chunk` {Buffer | String} Data to be written
-* `encoding` {String} Optional.  If `chunk` is a string, then encoding
-  defaults to `'utf8'`
-* `callback` {Function} Optional.  Called when this chunk is
-  successfully written.
-* Returns {Boolean}
-
-Writes `chunk` to the stream.  Returns `true` if the data has been
-flushed to the underlying resource.  Returns `false` to indicate that
-the buffer is full, and the data will be sent out in the future. The
-`'drain'` event will indicate when the buffer is empty again.
-
-The specifics of when `write()` will return false, is determined by
-the `highWaterMark` option provided to the constructor.
-
-### writable.end([chunk], [encoding], [callback])
-
-* `chunk` {Buffer | String} Optional final data to be written
-* `encoding` {String} Optional.  If `chunk` is a string, then encoding
-  defaults to `'utf8'`
-* `callback` {Function} Optional.  Called when the final chunk is
-  successfully written.
-
-Call this method to signal the end of the data being written to the
-stream.
-
-### Event: 'drain'
-
-Emitted when the stream's write queue empties and it's safe to write
-without buffering again. Listen for it when `stream.write()` returns
-`false`.
-
-### Event: 'close'
-
-Emitted when the underlying resource (for example, the backing file
-descriptor) has been closed. Not all streams will emit this.
-
-### Event: 'finish'
-
-When `end()` is called and there are no more chunks to write, this
-event is emitted.
-
-### Event: 'pipe'
-
-* `source` {Readable Stream}
-
-Emitted when the stream is passed to a readable stream's pipe method.
-
-### Event 'unpipe'
-
-* `source` {Readable Stream}
-
-Emitted when a previously established `pipe()` is removed using the
-source Readable stream's `unpipe()` method.
-
-## Class: stream.Duplex
-
-<!--type=class-->
-
-A "duplex" stream is one that is both Readable and Writable, such as a
-TCP socket connection.
-
-Note that `stream.Duplex` is an abstract class designed to be
-extended with an underlying implementation of the `_read(size)`
-and `_write(chunk, encoding, callback)` methods as you would with a Readable or
-Writable stream class.
-
-Since JavaScript doesn't have multiple prototypal inheritance, this
-class prototypally inherits from Readable, and then parasitically from
-Writable.  It is thus up to the user to implement both the lowlevel
-`_read(n)` method as well as the lowlevel `_write(chunk, encoding, cb)` method
-on extension duplex classes.
-
-### new stream.Duplex(options)
-
-* `options` {Object} Passed to both Writable and Readable
-  constructors. Also has the following fields:
-  * `allowHalfOpen` {Boolean} Default=true.  If set to `false`, then
-    the stream will automatically end the readable side when the
-    writable side ends and vice versa.
-
-In classes that extend the Duplex class, make sure to call the
-constructor so that the buffering settings can be properly
-initialized.
-
-## Class: stream.Transform
-
-A "transform" stream is a duplex stream where the output is causally
-connected in some way to the input, such as a zlib stream or a crypto
-stream.
-
-There is no requirement that the output be the same size as the input,
-the same number of chunks, or arrive at the same time.  For example, a
-Hash stream will only ever have a single chunk of output which is
-provided when the input is ended.  A zlib stream will either produce
-much smaller or much larger than its input.
-
-Rather than implement the `_read()` and `_write()` methods, Transform
-classes must implement the `_transform()` method, and may optionally
-also implement the `_flush()` method.  (See below.)
-
-### new stream.Transform([options])
-
-* `options` {Object} Passed to both Writable and Readable
-  constructors.
-
-In classes that extend the Transform class, make sure to call the
-constructor so that the buffering settings can be properly
-initialized.
-
-### transform.\_transform(chunk, encoding, callback)
-
-* `chunk` {Buffer | String} The chunk to be transformed.  Will always
-  be a buffer unless the `decodeStrings` option was set to `false`.
-* `encoding` {String} If the chunk is a string, then this is the
-  encoding type.  (Ignore if `decodeStrings` chunk is a buffer.)
-* `callback` {Function} Call this function (optionally with an error
-  argument) when you are done processing the supplied chunk.
-
-Note: **This function MUST NOT be called directly.**  It should be
-implemented by child classes, and called by the internal Transform
-class methods only.
-
-All Transform stream implementations must provide a `_transform`
-method to accept input and produce output.
-
-`_transform` should do whatever has to be done in this specific
-Transform class, to handle the bytes being written, and pass them off
-to the readable portion of the interface.  Do asynchronous I/O,
-process things, and so on.
-
-Call `transform.push(outputChunk)` 0 or more times to generate output
-from this input chunk, depending on how much data you want to output
-as a result of this chunk.
-
-Call the callback function only when the current chunk is completely
-consumed.  Note that there may or may not be output as a result of any
-particular input chunk.
-
-This method is prefixed with an underscore because it is internal to
-the class that defines it, and should not be called directly by user
-programs.  However, you **are** expected to override this method in
-your own extension classes.
-
-### transform.\_flush(callback)
-
-* `callback` {Function} Call this function (optionally with an error
-  argument) when you are done flushing any remaining data.
-
-Note: **This function MUST NOT be called directly.**  It MAY be implemented
-by child classes, and if so, will be called by the internal Transform
-class methods only.
-
-In some cases, your transform operation may need to emit a bit more
-data at the end of the stream.  For example, a `Zlib` compression
-stream will store up some internal state so that it can optimally
-compress the output.  At the end, however, it needs to do the best it
-can with what is left, so that the data will be complete.
-
-In those cases, you can implement a `_flush` method, which will be
-called at the very end, after all the written data is consumed, but
-before emitting `end` to signal the end of the readable side.  Just
-like with `_transform`, call `transform.push(chunk)` zero or more
-times, as appropriate, and call `callback` when the flush operation is
-complete.
-
-This method is prefixed with an underscore because it is internal to
-the class that defines it, and should not be called directly by user
-programs.  However, you **are** expected to override this method in
-your own extension classes.
-
-### Example: `SimpleProtocol` parser
-
-The example above of a simple protocol parser can be implemented much
-more simply by using the higher level `Transform` stream class.
-
-In this example, rather than providing the input as an argument, it
-would be piped into the parser, which is a more idiomatic Node stream
-approach.
-
-```javascript
-function SimpleProtocol(options) {
-  if (!(this instanceof SimpleProtocol))
-    return new SimpleProtocol(options);
-
-  Transform.call(this, options);
-  this._inBody = false;
-  this._sawFirstCr = false;
-  this._rawHeader = [];
-  this.header = null;
-}
-
-SimpleProtocol.prototype = Object.create(
-  Transform.prototype, { constructor: { value: SimpleProtocol }});
-
-SimpleProtocol.prototype._transform = function(chunk, encoding, done) {
-  if (!this._inBody) {
-    // check if the chunk has a \n\n
-    var split = -1;
-    for (var i = 0; i < chunk.length; i++) {
-      if (chunk[i] === 10) { // '\n'
-        if (this._sawFirstCr) {
-          split = i;
-          break;
-        } else {
-          this._sawFirstCr = true;
-        }
-      } else {
-        this._sawFirstCr = false;
-      }
-    }
-
-    if (split === -1) {
-      // still waiting for the \n\n
-      // stash the chunk, and try again.
-      this._rawHeader.push(chunk);
-    } else {
-      this._inBody = true;
-      var h = chunk.slice(0, split);
-      this._rawHeader.push(h);
-      var header = Buffer.concat(this._rawHeader).toString();
-      try {
-        this.header = JSON.parse(header);
-      } catch (er) {
-        this.emit('error', new Error('invalid simple protocol data'));
-        return;
-      }
-      // and let them know that we are done parsing the header.
-      this.emit('header', this.header);
-
-      // now, because we got some extra data, emit this first.
-      this.push(b);
-    }
-  } else {
-    // from there on, just provide the data to our consumer as-is.
-    this.push(b);
-  }
-  done();
-};
-
-var parser = new SimpleProtocol();
-source.pipe(parser)
-
-// Now parser is a readable stream that will emit 'header'
-// with the parsed header data.
-```
-
-
-## Class: stream.PassThrough
-
-This is a trivial implementation of a `Transform` stream that simply
-passes the input bytes across to the output.  Its purpose is mainly
-for examples and testing, but there are occasionally use cases where
-it can come in handy.

You can use it to have programs that\nhave to work with node v0.8, while being forward-compatible for v0.10\nand beyond.  When you drop support for v0.8, you can remove this\nmodule, and only use the native streams.\n\nThis is almost exactly the same codebase as appears in Node v0.10.\nHowever:\n\n1. The exported object is actually the Readable class.  Decorating the\n   native `stream` module would be global pollution.\n2. In v0.10, you can safely use `base64` as an argument to\n   `setEncoding` in Readable streams.  However, in v0.8, the\n   StringDecoder class has no `end()` method, which is problematic for\n   Base64.  So, don't use that, because it'll break and be weird.\n\nOther than that, the API is the same as `require('stream')` in v0.10,\nso the API docs are reproduced below.\n\n----------\n\n    Stability: 2 - Unstable\n\nA stream is an abstract interface implemented by various objects in\nNode.  For example a request to an HTTP server is a stream, as is\nstdout. Streams are readable, writable, or both. All streams are\ninstances of [EventEmitter][]\n\nYou can load the Stream base classes by doing `require('stream')`.\nThere are base classes provided for Readable streams, Writable\nstreams, Duplex streams, and Transform streams.\n\n## Compatibility\n\nIn earlier versions of Node, the Readable stream interface was\nsimpler, but also less powerful and less useful.\n\n* Rather than waiting for you to call the `read()` method, `'data'`\n  events would start emitting immediately.  If you needed to do some\n  I/O to decide how to handle data, then you had to store the chunks\n  in some kind of buffer so that they would not be lost.\n* The `pause()` method was advisory, rather than guaranteed.  This\n  meant that you still had to be prepared to receive `'data'` events\n  even when the stream was in a paused state.\n\nIn Node v0.10, the Readable class described below was added.  For\nbackwards compatibility with older Node programs, Readable streams\nswitch into \"old mode\" when a `'data'` event handler is added, or when\nthe `pause()` or `resume()` methods are called.  The effect is that,\neven if you are not using the new `read()` method and `'readable'`\nevent, you no longer have to worry about losing `'data'` chunks.\n\nMost programs will continue to function normally.  However, this\nintroduces an edge case in the following conditions:\n\n* No `'data'` event handler is added.\n* The `pause()` and `resume()` methods are never called.\n\nFor example, consider the following code:\n\n```javascript\n// WARNING!  BROKEN!\nnet.createServer(function(socket) {\n\n  // we add an 'end' method, but never consume the data\n  socket.on('end', function() {\n    // It will never get here.\n    socket.end('I got your message (but didnt read it)\\n');\n  });\n\n}).listen(1337);\n```\n\nIn versions of node prior to v0.10, the incoming message data would be\nsimply discarded.  However, in Node v0.10 and beyond, the socket will\nremain paused forever.\n\nThe workaround in this situation is to call the `resume()` method to\ntrigger \"old mode\" behavior:\n\n```javascript\n// Workaround\nnet.createServer(function(socket) {\n\n  socket.on('end', function() {\n    socket.end('I got your message (but didnt read it)\\n');\n  });\n\n  // start the flow of data, discarding it.\n  socket.resume();\n\n}).listen(1337);\n```\n\nIn addition to new Readable streams switching into old-mode, pre-v0.10\nstyle streams can be wrapped in a Readable class using the `wrap()`\nmethod.\n\n## Class: stream.Readable\n\n<!--type=class-->\n\nA `Readable Stream` has the following methods, members, and events.\n\nNote that `stream.Readable` is an abstract class designed to be\nextended with an underlying implementation of the `_read(size)`\nmethod. (See below.)\n\n### new stream.Readable([options])\n\n* `options` {Object}\n  * `highWaterMark` {Number} The maximum number of bytes to store in\n    the internal buffer before ceasing to read from the underlying\n    resource.  Default=16kb\n  * `encoding` {String} If specified, then buffers will be decoded to\n    strings using the specified encoding.  Default=null\n  * `objectMode` {Boolean} Whether this stream should behave\n    as a stream of objects. Meaning that stream.read(n) returns\n    a single value instead of a Buffer of size n\n\nIn classes that extend the Readable class, make sure to call the\nconstructor so that the buffering settings can be properly\ninitialized.\n\n### readable.\\_read(size)\n\n* `size` {Number} Number of bytes to read asynchronously\n\nNote: **This function should NOT be called directly.**  It should be\nimplemented by child classes, and called by the internal Readable\nclass methods only.\n\nAll Readable stream implementations must provide a `_read` method\nto fetch data from the underlying resource.\n\nThis method is prefixed with an underscore because it is internal to\nthe class that defines it, and should not be called directly by user\nprograms.  However, you **are** expected to override this method in\nyour own extension classes.\n\nWhen data is available, put it into the read queue by calling\n`readable.push(chunk)`.  If `push` returns false, then you should stop\nreading.  When `_read` is called again, you should start pushing more\ndata.\n\nThe `size` argument is advisory.  Implementations where a \"read\" is a\nsingle call that returns data can use this to know how much data to\nfetch.  Implementations where that is not relevant, such as TCP or\nTLS, may ignore this argument, and simply provide data whenever it\nbecomes available.  There is no need, for example to \"wait\" until\n`size` bytes are available before calling `stream.push(chunk)`.\n\n### readable.push(chunk)\n\n* `chunk` {Buffer | null | String} Chunk of data to push into the read queue\n* return {Boolean} Whether or not more pushes should be performed\n\nNote: **This function should be called by Readable implementors, NOT\nby consumers of Readable subclasses.**  The `_read()` function will not\nbe called again until at least one `push(chunk)` call is made.  If no\ndata is available, then you MAY call `push('')` (an empty string) to\nallow a future `_read` call, without adding any data to the queue.\n\nThe `Readable` class works by putting data into a read queue to be\npulled out later by calling the `read()` method when the `'readable'`\nevent fires.\n\nThe `push()` method will explicitly insert some data into the read\nqueue.  If it is called with `null` then it will signal the end of the\ndata.\n\nIn some cases, you may be wrapping a lower-level source which has some\nsort of pause/resume mechanism, and a data callback.  In those cases,\nyou could wrap the low-level source object by doing something like\nthis:\n\n```javascript\n// source is an object with readStop() and readStart() methods,\n// and an `ondata` member that gets called when it has data, and\n// an `onend` member that gets called when the data is over.\n\nvar stream = new Readable();\n\nsource.ondata = function(chunk) {\n  // if push() returns false, then we need to stop reading from source\n  if (!stream.push(chunk))\n    source.readStop();\n};\n\nsource.onend = function() {\n  stream.push(null);\n};\n\n// _read will be called when the stream wants to pull more data in\n// the advisory size argument is ignored in this case.\nstream._read = function(n) {\n  source.readStart();\n};\n```\n\n### readable.unshift(chunk)\n\n* `chunk` {Buffer | null | String} Chunk of data to unshift onto the read queue\n* return {Boolean} Whether or not more pushes should be performed\n\nThis is the corollary of `readable.push(chunk)`.  Rather than putting\nthe data at the *end* of the read queue, it puts it at the *front* of\nthe read queue.\n\nThis is useful in certain use-cases where a stream is being consumed\nby a parser, which needs to \"un-consume\" some data that it has\noptimistically pulled out of the source.\n\n```javascript\n// A parser for a simple data protocol.\n// The \"header\" is a JSON object, followed by 2 \\n characters, and\n// then a message body.\n//\n// Note: This can be done more simply as a Transform stream.  See below.\n\nfunction SimpleProtocol(source, options) {\n  if (!(this instanceof SimpleProtocol))\n    return new SimpleProtocol(options);\n\n  Readable.call(this, options);\n  this._inBody = false;\n  this._sawFirstCr = false;\n\n  // source is a readable stream, such as a socket or file\n  this._source = source;\n\n  var self = this;\n  source.on('end', function() {\n    self.push(null);\n  });\n\n  // give it a kick whenever the source is readable\n  // read(0) will not consume any bytes\n  source.on('readable', function() {\n    self.read(0);\n  });\n\n  this._rawHeader = [];\n  this.header = null;\n}\n\nSimpleProtocol.prototype = Object.create(\n  Readable.prototype, { constructor: { value: SimpleProtocol }});\n\nSimpleProtocol.prototype._read = function(n) {\n  if (!this._inBody) {\n    var chunk = this._source.read();\n\n    // if the source doesn't have data, we don't have data yet.\n    if (chunk === null)\n      return this.push('');\n\n    // check if the chunk has a \\n\\n\n    var split = -1;\n    for (var i = 0; i < chunk.length; i++) {\n      if (chunk[i] === 10) { // '\\n'\n        if (this._sawFirstCr) {\n          split = i;\n          break;\n        } else {\n          this._sawFirstCr = true;\n        }\n      } else {\n        this._sawFirstCr = false;\n      }\n    }\n\n    if (split === -1) {\n      // still waiting for the \\n\\n\n      // stash the chunk, and try again.\n      this._rawHeader.push(chunk);\n      this.push('');\n    } else {\n      this._inBody = true;\n      var h = chunk.slice(0, split);\n      this._rawHeader.push(h);\n      var header = Buffer.concat(this._rawHeader).toString();\n      try {\n        this.header = JSON.parse(header);\n      } catch (er) {\n        this.emit('error', new Error('invalid simple protocol data'));\n        return;\n      }\n      // now, because we got some extra data, unshift the rest\n      // back into the read queue so that our consumer will see it.\n      var b = chunk.slice(split);\n      this.unshift(b);\n\n      // and let them know that we are done parsing the header.\n      this.emit('header', this.header);\n    }\n  } else {\n    // from there on, just provide the data to our consumer.\n    // careful not to push(null), since that would indicate EOF.\n    var chunk = this._source.read();\n    if (chunk) this.push(chunk);\n  }\n};\n\n// Usage:\nvar parser = new SimpleProtocol(source);\n// Now parser is a readable stream that will emit 'header'\n// with the parsed header data.\n```\n\n### readable.wrap(stream)\n\n* `stream` {Stream} An \"old style\" readable stream\n\nIf you are using an older Node library that emits `'data'` events and\nhas a `pause()` method that is advisory only, then you can use the\n`wrap()` method to create a Readable stream that uses the old stream\nas its data source.\n\nFor example:\n\n```javascript\nvar OldReader = require('./old-api-module.js').OldReader;\nvar oreader = new OldReader;\nvar Readable = require('stream').Readable;\nvar myReader = new Readable().wrap(oreader);\n\nmyReader.on('readable', function() {\n  myReader.read(); // etc.\n});\n```\n\n### Event: 'readable'\n\nWhen there is data ready to be consumed, this event will fire.\n\nWhen this event emits, call the `read()` method to consume the data.\n\n### Event: 'end'\n\nEmitted when the stream has received an EOF (FIN in TCP terminology).\nIndicates that no more `'data'` events will happen. If the stream is\nalso writable, it may be possible to continue writing.\n\n### Event: 'data'\n\nThe `'data'` event emits either a `Buffer` (by default) or a string if\n`setEncoding()` was used.\n\nNote that adding a `'data'` event listener will switch the Readable\nstream into \"old mode\", where data is emitted as soon as it is\navailable, rather than waiting for you to call `read()` to consume it.\n\n### Event: 'error'\n\nEmitted if there was an error receiving data.\n\n### Event: 'close'\n\nEmitted when the underlying resource (for example, the backing file\ndescriptor) has been closed. Not all streams will emit this.\n\n### readable.setEncoding(encoding)\n\nMakes the `'data'` event emit a string instead of a `Buffer`. `encoding`\ncan be `'utf8'`, `'utf16le'` (`'ucs2'`), `'ascii'`, or `'hex'`.\n\nThe encoding can also be set by specifying an `encoding` field to the\nconstructor.\n\n### readable.read([size])\n\n* `size` {Number | null} Optional number of bytes to read.\n* Return: {Buffer | String | null}\n\nNote: **This function SHOULD be called by Readable stream users.**\n\nCall this method to consume data once the `'readable'` event is\nemitted.\n\nThe `size` argument will set a minimum number of bytes that you are\ninterested in.  If not set, then the entire content of the internal\nbuffer is returned.\n\nIf there is no data to consume, or if there are fewer bytes in the\ninternal buffer than the `size` argument, then `null` is returned, and\na future `'readable'` event will be emitted when more is available.\n\nCalling `stream.read(0)` will always return `null`, and will trigger a\nrefresh of the internal buffer, but otherwise be a no-op.\n\n### readable.pipe(destination, [options])\n\n* `destination` {Writable Stream}\n* `options` {Object} Optional\n  * `end` {Boolean} Default=true\n\nConnects this readable stream to `destination` WriteStream. Incoming\ndata on this stream gets written to `destination`.  Properly manages\nback-pressure so that a slow destination will not be overwhelmed by a\nfast readable stream.\n\nThis function returns the `destination` stream.\n\nFor example, emulating the Unix `cat` command:\n\n    process.stdin.pipe(process.stdout);\n\nBy default `end()` is called on the destination when the source stream\nemits `end`, so that `destination` is no longer writable. Pass `{ end:\nfalse }` as `options` to keep the destination stream open.\n\nThis keeps `writer` open so that \"Goodbye\" can be written at the\nend.\n\n    reader.pipe(writer, { end: false });\n    reader.on(\"end\", function() {\n      writer.end(\"Goodbye\\n\");\n    });\n\nNote that `process.stderr` and `process.stdout` are never closed until\nthe process exits, regardless of the specified options.\n\n### readable.unpipe([destination])\n\n* `destination` {Writable Stream} Optional\n\nUndo a previously established `pipe()`.  If no destination is\nprovided, then all previously established pipes are removed.\n\n### readable.pause()\n\nSwitches the readable stream into \"old mode\", where data is emitted\nusing a `'data'` event rather than being buffered for consumption via\nthe `read()` method.\n\nCeases the flow of data.  No `'data'` events are emitted while the\nstream is in a paused state.\n\n### readable.resume()\n\nSwitches the readable stream into \"old mode\", where data is emitted\nusing a `'data'` event rather than being buffered for consumption via\nthe `read()` method.\n\nResumes the incoming `'data'` events after a `pause()`.\n\n\n## Class: stream.Writable\n\n<!--type=class-->\n\nA `Writable` Stream has the following methods, members, and events.\n\nNote that `stream.Writable` is an abstract class designed to be\nextended with an underlying implementation of the\n`_write(chunk, encoding, cb)` method. (See below.)\n\n### new stream.Writable([options])\n\n* `options` {Object}\n  * `highWaterMark` {Number} Buffer level when `write()` starts\n    returning false. Default=16kb\n  * `decodeStrings` {Boolean} Whether or not to decode strings into\n    Buffers before passing them to `_write()`.  Default=true\n\nIn classes that extend the Writable class, make sure to call the\nconstructor so that the buffering settings can be properly\ninitialized.\n\n### writable.\\_write(chunk, encoding, callback)\n\n* `chunk` {Buffer | String} The chunk to be written.  Will always\n  be a buffer unless the `decodeStrings` option was set to `false`.\n* `encoding` {String} If the chunk is a string, then this is the\n  encoding type.  Ignore chunk is a buffer.  Note that chunk will\n  **always** be a buffer unless the `decodeStrings` option is\n  explicitly set to `false`.\n* `callback` {Function} Call this function (optionally with an error\n  argument) when you are done processing the supplied chunk.\n\nAll Writable stream implementations must provide a `_write` method to\nsend data to the underlying resource.\n\nNote: **This function MUST NOT be called directly.**  It should be\nimplemented by child classes, and called by the internal Writable\nclass methods only.\n\nCall the callback using the standard `callback(error)` pattern to\nsignal that the write completed successfully or with an error.\n\nIf the `decodeStrings` flag is set in the constructor options, then\n`chunk` may be a string rather than a Buffer, and `encoding` will\nindicate the sort of string that it is.  This is to support\nimplementations that have an optimized handling for certain string\ndata encodings.  If you do not explicitly set the `decodeStrings`\noption to `false`, then you can safely ignore the `encoding` argument,\nand assume that `chunk` will always be a Buffer.\n\nThis method is prefixed with an underscore because it is internal to\nthe class that defines it, and should not be called directly by user\nprograms.  However, you **are** expected to override this method in\nyour own extension classes.\n\n\n### writable.write(chunk, [encoding], [callback])\n\n* `chunk` {Buffer | String} Data to be written\n* `encoding` {String} Optional.  If `chunk` is a string, then encoding\n  defaults to `'utf8'`\n* `callback` {Function} Optional.  Called when this chunk is\n  successfully written.\n* Returns {Boolean}\n\nWrites `chunk` to the stream.  Returns `true` if the data has been\nflushed to the underlying resource.  Returns `false` to indicate that\nthe buffer is full, and the data will be sent out in the future. The\n`'drain'` event will indicate when the buffer is empty again.\n\nThe specifics of when `write()` will return false, is determined by\nthe `highWaterMark` option provided to the constructor.\n\n### writable.end([chunk], [encoding], [callback])\n\n* `chunk` {Buffer | String} Optional final data to be written\n* `encoding` {String} Optional.  If `chunk` is a string, then encoding\n  defaults to `'utf8'`\n* `callback` {Function} Optional.  Called when the final chunk is\n  successfully written.\n\nCall this method to signal the end of the data being written to the\nstream.\n\n### Event: 'drain'\n\nEmitted when the stream's write queue empties and it's safe to write\nwithout buffering again. Listen for it when `stream.write()` returns\n`false`.\n\n### Event: 'close'\n\nEmitted when the underlying resource (for example, the backing file\ndescriptor) has been closed. Not all streams will emit this.\n\n### Event: 'finish'\n\nWhen `end()` is called and there are no more chunks to write, this\nevent is emitted.\n\n### Event: 'pipe'\n\n* `source` {Readable Stream}\n\nEmitted when the stream is passed to a readable stream's pipe method.\n\n### Event 'unpipe'\n\n* `source` {Readable Stream}\n\nEmitted when a previously established `pipe()` is removed using the\nsource Readable stream's `unpipe()` method.\n\n## Class: stream.Duplex\n\n<!--type=class-->\n\nA \"duplex\" stream is one that is both Readable and Writable, such as a\nTCP socket connection.\n\nNote that `stream.Duplex` is an abstract class designed to be\nextended with an underlying implementation of the `_read(size)`\nand `_write(chunk, encoding, callback)` methods as you would with a Readable or\nWritable stream class.\n\nSince JavaScript doesn't have multiple prototypal inheritance, this\nclass prototypally inherits from Readable, and then parasitically from\nWritable.  It is thus up to the user to implement both the lowlevel\n`_read(n)` method as well as the lowlevel `_write(chunk, encoding, cb)` method\non extension duplex classes.\n\n### new stream.Duplex(options)\n\n* `options` {Object} Passed to both Writable and Readable\n  constructors. Also has the following fields:\n  * `allowHalfOpen` {Boolean} Default=true.  If set to `false`, then\n    the stream will automatically end the readable side when the\n    writable side ends and vice versa.\n\nIn classes that extend the Duplex class, make sure to call the\nconstructor so that the buffering settings can be properly\ninitialized.\n\n## Class: stream.Transform\n\nA \"transform\" stream is a duplex stream where the output is causally\nconnected in some way to the input, such as a zlib stream or a crypto\nstream.\n\nThere is no requirement that the output be the same size as the input,\nthe same number of chunks, or arrive at the same time.  For example, a\nHash stream will only ever have a single chunk of output which is\nprovided when the input is ended.  A zlib stream will either produce\nmuch smaller or much larger than its input.\n\nRather than implement the `_read()` and `_write()` methods, Transform\nclasses must implement the `_transform()` method, and may optionally\nalso implement the `_flush()` method.  (See below.)\n\n### new stream.Transform([options])\n\n* `options` {Object} Passed to both Writable and Readable\n  constructors.\n\nIn classes that extend the Transform class, make sure to call the\nconstructor so that the buffering settings can be properly\ninitialized.\n\n### transform.\\_transform(chunk, encoding, callback)\n\n* `chunk` {Buffer | String} The chunk to be transformed.  Will always\n  be a buffer unless the `decodeStrings` option was set to `false`.\n* `encoding` {String} If the chunk is a string, then this is the\n  encoding type.  (Ignore if `decodeStrings` chunk is a buffer.)\n* `callback` {Function} Call this function (optionally with an error\n  argument) when you are done processing the supplied chunk.\n\nNote: **This function MUST NOT be called directly.**  It should be\nimplemented by child classes, and called by the internal Transform\nclass methods only.\n\nAll Transform stream implementations must provide a `_transform`\nmethod to accept input and produce output.\n\n`_transform` should do whatever has to be done in this specific\nTransform class, to handle the bytes being written, and pass them off\nto the readable portion of the interface.  Do asynchronous I/O,\nprocess things, and so on.\n\nCall `transform.push(outputChunk)` 0 or more times to generate output\nfrom this input chunk, depending on how much data you want to output\nas a result of this chunk.\n\nCall the callback function only when the current chunk is completely\nconsumed.  Note that there may or may not be output as a result of any\nparticular input chunk.\n\nThis method is prefixed with an underscore because it is internal to\nthe class that defines it, and should not be called directly by user\nprograms.  However, you **are** expected to override this method in\nyour own extension classes.\n\n### transform.\\_flush(callback)\n\n* `callback` {Function} Call this function (optionally with an error\n  argument) when you are done flushing any remaining data.\n\nNote: **This function MUST NOT be called directly.**  It MAY be implemented\nby child classes, and if so, will be called by the internal Transform\nclass methods only.\n\nIn some cases, your transform operation may need to emit a bit more\ndata at the end of the stream.  For example, a `Zlib` compression\nstream will store up some internal state so that it can optimally\ncompress the output.  At the end, however, it needs to do the best it\ncan with what is left, so that the data will be complete.\n\nIn those cases, you can implement a `_flush` method, which will be\ncalled at the very end, after all the written data is consumed, but\nbefore emitting `end` to signal the end of the readable side.  Just\nlike with `_transform`, call `transform.push(chunk)` zero or more\ntimes, as appropriate, and call `callback` when the flush operation is\ncomplete.\n\nThis method is prefixed with an underscore because it is internal to\nthe class that defines it, and should not be called directly by user\nprograms.  However, you **are** expected to override this method in\nyour own extension classes.\n\n### Example: `SimpleProtocol` parser\n\nThe example above of a simple protocol parser can be implemented much\nmore simply by using the higher level `Transform` stream class.\n\nIn this example, rather than providing the input as an argument, it\nwould be piped into the parser, which is a more idiomatic Node stream\napproach.\n\n```javascript\nfunction SimpleProtocol(options) {\n  if (!(this instanceof SimpleProtocol))\n    return new SimpleProtocol(options);\n\n  Transform.call(this, options);\n  this._inBody = false;\n  this._sawFirstCr = false;\n  this._rawHeader = [];\n  this.header = null;\n}\n\nSimpleProtocol.prototype = Object.create(\n  Transform.prototype, { constructor: { value: SimpleProtocol }});\n\nSimpleProtocol.prototype._transform = function(chunk, encoding, done) {\n  if (!this._inBody) {\n    // check if the chunk has a \\n\\n\n    var split = -1;\n    for (var i = 0; i < chunk.length; i++) {\n      if (chunk[i] === 10) { // '\\n'\n        if (this._sawFirstCr) {\n          split = i;\n          break;\n        } else {\n          this._sawFirstCr = true;\n        }\n      } else {\n        this._sawFirstCr = false;\n      }\n    }\n\n    if (split === -1) {\n      // still waiting for the \\n\\n\n      // stash the chunk, and try again.\n      this._rawHeader.push(chunk);\n    } else {\n      this._inBody = true;\n      var h = chunk.slice(0, split);\n      this._rawHeader.push(h);\n      var header = Buffer.concat(this._rawHeader).toString();\n      try {\n        this.header = JSON.parse(header);\n      } catch (er) {\n        this.emit('error', new Error('invalid simple protocol data'));\n        return;\n      }\n      // and let them know that we are done parsing the header.\n      this.emit('header', this.header);\n\n      // now, because we got some extra data, emit this first.\n      this.push(b);\n    }\n  } else {\n    // from there on, just provide the data to our consumer as-is.\n    this.push(b);\n  }\n  done();\n};\n\nvar parser = new SimpleProtocol();\nsource.pipe(parser)\n\n// Now parser is a readable stream that will emit 'header'\n// with the parsed header data.\n```\n\n\n## Class: stream.PassThrough\n\nThis is a trivial implementation of a `Transform` stream that simply\npasses the input bytes across to the output.  Its purpose is mainly\nfor examples and testing, but there are occasionally use cases where\nit can come in handy.\n\n\n[EventEmitter]: events.html#events_class_events_eventemitter\n",

The former tracks the Streams2 implementation in Node 0.10, including bug-fixes and minor improvements as they are added. The latter tracks Streams3 as it develops in Node 0.11; we will likely see a v1.2.x branch for Node 0.12.\n\n**readable-stream** uses proper patch-level versioning so if you pin to `\"~1.0.0\"` you’ll get the latest Node 0.10 Streams2 implementation, including any fixes and minor non-breaking improvements. The patch-level versions of 1.0.x and 1.1.x should mirror the patch-level versions of Node-core releases. You should prefer the **1.0.x** releases for now and when you’re ready to start using Streams3, pin to `\"~1.1.0\"`\n\n",

This way AngularJS doesn't need to\nrequest the actual HTML files anymore.\n\n## Usage\n\nFirst, install `gulp-ng-html2js` as a development dependency:\n\n```shell\nnpm install --save-dev gulp-ng-html2js\n```\n\nThen, add it to your `gulpfile.js`:\n\n```javascript\nvar ngHtml2Js = require(\"gulp-ng-html2js\");\n\ngulp.src(\"./partials/*.html\")\n\t.pipe(ngHtml2Js({\n\t\tmoduleName: \"MyAwesomePartials\",\n\t\tprefix: \"/partials\"\n\t}))\n\t.pipe(gulp.dest(\"./dist/partials\"));\n```\n\nThe main reason to use this module would be optimization. By pre-loading the HTML files, you can spare requests and\nloading time when the files are actually needed. When you are optimizing, you should do it properly. So, we should add\nthe following plugins: `gulp-minify-html`, `gulp-uglify`, and `gulp-concat`:\n\n```javascript\nvar ngHtml2Js = require(\"gulp-ng-html2js\");\nvar minifyHtml = require(\"gulp-minify-html\");\nvar concat = require(\"gulp-concat\");\nvar uglify = require(\"gulp-uglify\");\n\ngulp.src(\"./partials/*.html\")\n\t.pipe(minifyHtml({\n\t\tempty: true,\n\t\tspare: true,\n\t\tquotes: true\n\t}))\n\t.pipe(ngHtml2Js({\n\t\tmoduleName: \"MyAwesomePartials\",\n\t\tprefix: \"/partials\"\n\t}))\n\t.pipe(concat(\"partials.min.js\"))\n\t.pipe(uglify())\n\t.pipe(gulp.dest(\"./dist/partials\"));\n```\n\nThis way you end up with 1 single, minified Javascript file, which pre-loads all the (minified) HTML templates.\n\n## API\n\n### ngHtml2Js(options)\n\n#### options.moduleName\nType: `String`\n\nThe name of the generated AngularJS module.

This way AngularJS doesn't need to\r\nrequest the actual HTML files anymore.\r\n\r\n## Usage\r\n\r\nFirst, install `gulp-ng-html2js` as a development dependency:\r\n\r\n```shell\r\nnpm install --save-dev gulp-ng-html2js\r\n```\r\n\r\nThen, add it to your `gulpfile.js`:\r\n\r\n```javascript\r\nvar ngHtml2Js = require(\"gulp-ng-html2js\");\r\n\r\ngulp.src(\"./partials/*.html\")\r\n\t.pipe(ngHtml2Js({\r\n\t\tmoduleName: \"MyAwesomePartials\",\r\n\t\tprefix: \"/partials\"\r\n\t}))\r\n\t.pipe(gulp.dest(\"./dist/partials\"));\r\n```\r\n\r\nThe main reason to use this module would be optimization. By pre-loading the HTML files, you can spare requests and\r\nloading time when the files are actually needed. When you are optimizing, you should do it properly. So, we should add\r\nthe following plugins: `gulp-minify-html`, `gulp-uglify`, and `gulp-concat`:\r\n\r\n```javascript\r\nvar ngHtml2Js = require(\"gulp-ng-html2js\");\r\nvar minifyHtml = require(\"gulp-minify-html\");\r\nvar concat = require(\"gulp-concat\");\r\nvar uglify = require(\"gulp-uglify\");\r\n\r\ngulp.src(\"./partials/*.html\")\r\n\t.pipe(minifyHtml({\r\n\t\tempty: true,\r\n\t\tspare: true,\r\n\t\tquotes: true\r\n\t}))\r\n\t.pipe(ngHtml2Js({\r\n\t\tmoduleName: \"MyAwesomePartials\",\r\n\t\tprefix: \"/partials\"\r\n\t}))\r\n\t.pipe(concat(\"partials.min.js\"))\r\n\t.pipe(uglify())\r\n\t.pipe(gulp.dest(\"./dist/partials\"));\r\n```\r\n\r\nThis way you end up with 1 single, minified Javascript file, which pre-loads all the (minified) HTML templates.\r\n\r\n## API\r\n\r\n### ngHtml2Js(options)\r\n\r\n#### options.moduleName\r\nType: `String`\r\n\r\nThe name of the generated AngularJS module. Uses the file url if omitted.\r\n\r\n#### options.prefix\r\nType: `String`\r\n\r\nThe prefix which should be prepended to the file path to generate the file url.\r\n\r\n#### options.stripPrefix\r\nType: `String`\r\n\r\nThe prefix which should be subtracted from the file path to generate the file url.\r\n\r\n#### options.rename\r\nType: `Function`\r\n\r\nA function that allows the generate file url to be manipulated. For example:\r\n\r\n```\r\nfunction (url) {\r\n  return url.replace('.tpl.html', '.html');\r\n}\r\n```\r\n\r\n## License\r\n\r\n[MIT License](http://en.wikipedia.org/wiki/MIT_License)\r\n\r\n[npm-url]: https://npmjs.org/package/gulp-ng-html2js\r\n[npm-image]: https://badge.fury.io/js/gulp-ng-html2js.png\r\n\r\n[travis-url]: http://travis-ci.org/marklagendijk/gulp-ng-html2js\r\n[travis-image]: https://secure.travis-ci.org/marklagendijk/gulp-ng-html2js.png?branch=master\r\n\r\n[depstat-url]: https://david-dm.org/marklagendijk/gulp-ng-html2js\r\n[depstat-image]: https://david-dm.org/marklagendijk/gulp-ng-html2js.png\r\n",

 # readable-stream
 
-A new class of streams for Node.js
+***Node-core streams for userland***
 
-This module provides the new Stream base classes introduced in Node
-v0.10, for use in Node v0.8.  You can use it to have programs that
-have to work with node v0.8, while being forward-compatible for v0.10
-and beyond.  When you drop support for v0.8, you can remove this
-module, and only use the native streams.
+[![NPM](https://nodei.co/npm/readable-stream.png?downloads=true)](https://nodei.co/npm/readable-stream/)
+[![NPM](https://nodei.co/npm-dl/readable-stream.png)](https://nodei.co/npm/readable-stream/)
 
-This is almost exactly the same codebase as appears in Node v0.10.
-However:
+This package is a mirror of the Streams2 and Streams3 implementations in Node-core.
 
-1. The exported object is actually the Readable class.  Decorating the
-   native `stream` module would be global pollution.
-2. In v0.10, you can safely use `base64` as an argument to
-   `setEncoding` in Readable streams.  However, in v0.8, the
-   StringDecoder class has no `end()` method, which is problematic for
-   Base64.  So, don't use that, because it'll break and be weird.
+If you want to guarantee a stable streams base, regardless of what version of Node you, or the users of your libraries are using, use **readable-stream** *only* and avoid the *"stream"* module in Node-core.
 
-Other than that, the API is the same as `require('stream')` in v0.10,
-so the API docs are reproduced below.
+**readable-stream** comes in two major versions, v1.0.x and v1.1.x. The former tracks the Streams2 implementation in Node 0.10, including bug-fixes and minor improvements as they are added. The latter tracks Streams3 as it develops in Node 0.11; we will likely see a v1.2.x branch for Node 0.12.
 
-----------
+**readable-stream** uses proper patch-level versioning so if you pin to `"~1.0.0"` you’ll get the latest Node 0.10 Streams2 implementation, including any fixes and minor non-breaking improvements. The patch-level versions of 1.0.x and 1.1.x should mirror the patch-level versions of Node-core releases. You should prefer the **1.0.x** releases for now and when you’re ready to start using Streams3, pin to `"~1.1.0"`
 
-    Stability: 2 - Unstable
-
-A stream is an abstract interface implemented by various objects in
-Node.  For example a request to an HTTP server is a stream, as is
-stdout. Streams are readable, writable, or both. All streams are
-instances of [EventEmitter][]
-
-You can load the Stream base classes by doing `require('stream')`.
-There are base classes provided for Readable streams, Writable
-streams, Duplex streams, and Transform streams.
-
-## Compatibility
-
-In earlier versions of Node, the Readable stream interface was
-simpler, but also less powerful and less useful.
-
-* Rather than waiting for you to call the `read()` method, `'data'`
-  events would start emitting immediately.  If you needed to do some
-  I/O to decide how to handle data, then you had to store the chunks
-  in some kind of buffer so that they would not be lost.
-* The `pause()` method was advisory, rather than guaranteed.  This
-  meant that you still had to be prepared to receive `'data'` events
-  even when the stream was in a paused state.
-
-In Node v0.10, the Readable class described below was added.  For
-backwards compatibility with older Node programs, Readable streams
-switch into "old mode" when a `'data'` event handler is added, or when
-the `pause()` or `resume()` methods are called.  The effect is that,
-even if you are not using the new `read()` method and `'readable'`
-event, you no longer have to worry about losing `'data'` chunks.
-
-Most programs will continue to function normally.  However, this
-introduces an edge case in the following conditions:
-
-* No `'data'` event handler is added.
-* The `pause()` and `resume()` methods are never called.
-
-For example, consider the following code:
-
-```javascript
-// WARNING!  BROKEN!
-net.createServer(function(socket) {
-
-  // we add an 'end' method, but never consume the data
-  socket.on('end', function() {
-    // It will never get here.
-    socket.end('I got your message (but didnt read it)\n');
-  });
-
-}).listen(1337);
-```
-
-In versions of node prior to v0.10, the incoming message data would be
-simply discarded.  However, in Node v0.10 and beyond, the socket will
-remain paused forever.
-
-The workaround in this situation is to call the `resume()` method to
-trigger "old mode" behavior:
-
-```javascript
-// Workaround
-net.createServer(function(socket) {
-
-  socket.on('end', function() {
-    socket.end('I got your message (but didnt read it)\n');
-  });
-
-  // start the flow of data, discarding it.
-  socket.resume();
-
-}).listen(1337);
-```
-
-In addition to new Readable streams switching into old-mode, pre-v0.10
-style streams can be wrapped in a Readable class using the `wrap()`
-method.
-
-## Class: stream.Readable
-
-<!--type=class-->
-
-A `Readable Stream` has the following methods, members, and events.
-
-Note that `stream.Readable` is an abstract class designed to be
-extended with an underlying implementation of the `_read(size)`
-method. (See below.)
-
-### new stream.Readable([options])
-
-* `options` {Object}
-  * `highWaterMark` {Number} The maximum number of bytes to store in
-    the internal buffer before ceasing to read from the underlying
-    resource.  Default=16kb
-  * `encoding` {String} If specified, then buffers will be decoded to
-    strings using the specified encoding.  Default=null
-  * `objectMode` {Boolean} Whether this stream should behave
-    as a stream of objects. Meaning that stream.read(n) returns
-    a single value instead of a Buffer of size n
-
-In classes that extend the Readable class, make sure to call the
-constructor so that the buffering settings can be properly
-initialized.
-
-### readable.\_read(size)
-
-* `size` {Number} Number of bytes to read asynchronously
-
-Note: **This function should NOT be called directly.**  It should be
-implemented by child classes, and called by the internal Readable
-class methods only.
-
-All Readable stream implementations must provide a `_read` method
-to fetch data from the underlying resource.
-
-This method is prefixed with an underscore because it is internal to
-the class that defines it, and should not be called directly by user
-programs.  However, you **are** expected to override this method in
-your own extension classes.
-
-When data is available, put it into the read queue by calling
-`readable.push(chunk)`.  If `push` returns false, then you should stop
-reading.  When `_read` is called again, you should start pushing more
-data.
-
-The `size` argument is advisory.  Implementations where a "read" is a
-single call that returns data can use this to know how much data to
-fetch.  Implementations where that is not relevant, such as TCP or
-TLS, may ignore this argument, and simply provide data whenever it
-becomes available.  There is no need, for example to "wait" until
-`size` bytes are available before calling `stream.push(chunk)`.
-
-### readable.push(chunk)
-
-* `chunk` {Buffer | null | String} Chunk of data to push into the read queue
-* return {Boolean} Whether or not more pushes should be performed
-
-Note: **This function should be called by Readable implementors, NOT
-by consumers of Readable subclasses.**  The `_read()` function will not
-be called again until at least one `push(chunk)` call is made.  If no
-data is available, then you MAY call `push('')` (an empty string) to
-allow a future `_read` call, without adding any data to the queue.
-
-The `Readable` class works by putting data into a read queue to be
-pulled out later by calling the `read()` method when the `'readable'`
-event fires.
-
-The `push()` method will explicitly insert some data into the read
-queue.  If it is called with `null` then it will signal the end of the
-data.
-
-In some cases, you may be wrapping a lower-level source which has some
-sort of pause/resume mechanism, and a data callback.  In those cases,
-you could wrap the low-level source object by doing something like
-this:
-
-```javascript
-// source is an object with readStop() and readStart() methods,
-// and an `ondata` member that gets called when it has data, and
-// an `onend` member that gets called when the data is over.
-
-var stream = new Readable();
-
-source.ondata = function(chunk) {
-  // if push() returns false, then we need to stop reading from source
-  if (!stream.push(chunk))
-    source.readStop();
-};
-
-source.onend = function() {
-  stream.push(null);
-};
-
-// _read will be called when the stream wants to pull more data in
-// the advisory size argument is ignored in this case.
-stream._read = function(n) {
-  source.readStart();
-};
-```
-
-### readable.unshift(chunk)
-
-* `chunk` {Buffer | null | String} Chunk of data to unshift onto the read queue
-* return {Boolean} Whether or not more pushes should be performed
-
-This is the corollary of `readable.push(chunk)`.  Rather than putting
-the data at the *end* of the read queue, it puts it at the *front* of
-the read queue.
-
-This is useful in certain use-cases where a stream is being consumed
-by a parser, which needs to "un-consume" some data that it has
-optimistically pulled out of the source.
-
-```javascript
-// A parser for a simple data protocol.
-// The "header" is a JSON object, followed by 2 \n characters, and
-// then a message body.
-//
-// Note: This can be done more simply as a Transform stream.  See below.
-
-function SimpleProtocol(source, options) {
-  if (!(this instanceof SimpleProtocol))
-    return new SimpleProtocol(options);
-
-  Readable.call(this, options);
-  this._inBody = false;
-  this._sawFirstCr = false;
-
-  // source is a readable stream, such as a socket or file
-  this._source = source;
-
-  var self = this;
-  source.on('end', function() {
-    self.push(null);
-  });
-
-  // give it a kick whenever the source is readable
-  // read(0) will not consume any bytes
-  source.on('readable', function() {
-    self.read(0);
-  });
-
-  this._rawHeader = [];
-  this.header = null;
-}
-
-SimpleProtocol.prototype = Object.create(
-  Readable.prototype, { constructor: { value: SimpleProtocol }});
-
-SimpleProtocol.prototype._read = function(n) {
-  if (!this._inBody) {
-    var chunk = this._source.read();
-
-    // if the source doesn't have data, we don't have data yet.
-    if (chunk === null)
-      return this.push('');
-
-    // check if the chunk has a \n\n
-    var split = -1;
-    for (var i = 0; i < chunk.length; i++) {
-      if (chunk[i] === 10) { // '\n'
-        if (this._sawFirstCr) {
-          split = i;
-          break;
-        } else {
-          this._sawFirstCr = true;
-        }
-      } else {
-        this._sawFirstCr = false;
-      }
-    }
-
-    if (split === -1) {
-      // still waiting for the \n\n
-      // stash the chunk, and try again.
-      this._rawHeader.push(chunk);
-      this.push('');
-    } else {
-      this._inBody = true;
-      var h = chunk.slice(0, split);
-      this._rawHeader.push(h);
-      var header = Buffer.concat(this._rawHeader).toString();
-      try {
-        this.header = JSON.parse(header);
-      } catch (er) {
-        this.emit('error', new Error('invalid simple protocol data'));
-        return;
-      }
-      // now, because we got some extra data, unshift the rest
-      // back into the read queue so that our consumer will see it.
-      var b = chunk.slice(split);
-      this.unshift(b);
-
-      // and let them know that we are done parsing the header.
-      this.emit('header', this.header);
-    }
-  } else {
-    // from there on, just provide the data to our consumer.
-    // careful not to push(null), since that would indicate EOF.
-    var chunk = this._source.read();
-    if (chunk) this.push(chunk);
-  }
-};
-
-// Usage:
-var parser = new SimpleProtocol(source);
-// Now parser is a readable stream that will emit 'header'
-// with the parsed header data.
-```
-
-### readable.wrap(stream)
-
-* `stream` {Stream} An "old style" readable stream
-
-If you are using an older Node library that emits `'data'` events and
-has a `pause()` method that is advisory only, then you can use the
-`wrap()` method to create a Readable stream that uses the old stream
-as its data source.
-
-For example:
-
-```javascript
-var OldReader = require('./old-api-module.js').OldReader;
-var oreader = new OldReader;
-var Readable = require('stream').Readable;
-var myReader = new Readable().wrap(oreader);
-
-myReader.on('readable', function() {
-  myReader.read(); // etc.
-});
-```
-
-### Event: 'readable'
-
-When there is data ready to be consumed, this event will fire.
-
-When this event emits, call the `read()` method to consume the data.
-
-### Event: 'end'
-
-Emitted when the stream has received an EOF (FIN in TCP terminology).
-Indicates that no more `'data'` events will happen. If the stream is
-also writable, it may be possible to continue writing.
-
-### Event: 'data'
-
-The `'data'` event emits either a `Buffer` (by default) or a string if
-`setEncoding()` was used.
-
-Note that adding a `'data'` event listener will switch the Readable
-stream into "old mode", where data is emitted as soon as it is
-available, rather than waiting for you to call `read()` to consume it.
-
-### Event: 'error'
-
-Emitted if there was an error receiving data.
-
-### Event: 'close'
-
-Emitted when the underlying resource (for example, the backing file
-descriptor) has been closed. Not all streams will emit this.
-
-### readable.setEncoding(encoding)
-
-Makes the `'data'` event emit a string instead of a `Buffer`. `encoding`
-can be `'utf8'`, `'utf16le'` (`'ucs2'`), `'ascii'`, or `'hex'`.
-
-The encoding can also be set by specifying an `encoding` field to the
-constructor.
-
-### readable.read([size])
-
-* `size` {Number | null} Optional number of bytes to read.
-* Return: {Buffer | String | null}
-
-Note: **This function SHOULD be called by Readable stream users.**
-
-Call this method to consume data once the `'readable'` event is
-emitted.
-
-The `size` argument will set a minimum number of bytes that you are
-interested in.  If not set, then the entire content of the internal
-buffer is returned.
-
-If there is no data to consume, or if there are fewer bytes in the
-internal buffer than the `size` argument, then `null` is returned, and
-a future `'readable'` event will be emitted when more is available.
-
-Calling `stream.read(0)` will always return `null`, and will trigger a
-refresh of the internal buffer, but otherwise be a no-op.
-
-### readable.pipe(destination, [options])
-
-* `destination` {Writable Stream}
-* `options` {Object} Optional
-  * `end` {Boolean} Default=true
-
-Connects this readable stream to `destination` WriteStream. Incoming
-data on this stream gets written to `destination`.  Properly manages
-back-pressure so that a slow destination will not be overwhelmed by a
-fast readable stream.
-
-This function returns the `destination` stream.
-
-For example, emulating the Unix `cat` command:
-
-    process.stdin.pipe(process.stdout);
-
-By default `end()` is called on the destination when the source stream
-emits `end`, so that `destination` is no longer writable. Pass `{ end:
-false }` as `options` to keep the destination stream open.
-
-This keeps `writer` open so that "Goodbye" can be written at the
-end.
-
-    reader.pipe(writer, { end: false });
-    reader.on("end", function() {
-      writer.end("Goodbye\n");
-    });
-
-Note that `process.stderr` and `process.stdout` are never closed until
-the process exits, regardless of the specified options.
-
-### readable.unpipe([destination])
-
-* `destination` {Writable Stream} Optional
-
-Undo a previously established `pipe()`.  If no destination is
-provided, then all previously established pipes are removed.
-
-### readable.pause()
-
-Switches the readable stream into "old mode", where data is emitted
-using a `'data'` event rather than being buffered for consumption via
-the `read()` method.
-
-Ceases the flow of data.  No `'data'` events are emitted while the
-stream is in a paused state.
-
-### readable.resume()
-
-Switches the readable stream into "old mode", where data is emitted
-using a `'data'` event rather than being buffered for consumption via
-the `read()` method.
-
-Resumes the incoming `'data'` events after a `pause()`.
-
-
-## Class: stream.Writable
-
-<!--type=class-->
-
-A `Writable` Stream has the following methods, members, and events.
-
-Note that `stream.Writable` is an abstract class designed to be
-extended with an underlying implementation of the
-`_write(chunk, encoding, cb)` method. (See below.)
-
-### new stream.Writable([options])
-
-* `options` {Object}
-  * `highWaterMark` {Number} Buffer level when `write()` starts
-    returning false. Default=16kb
-  * `decodeStrings` {Boolean} Whether or not to decode strings into
-    Buffers before passing them to `_write()`.  Default=true
-
-In classes that extend the Writable class, make sure to call the
-constructor so that the buffering settings can be properly
-initialized.
-
-### writable.\_write(chunk, encoding, callback)
-
-* `chunk` {Buffer | String} The chunk to be written.  Will always
-  be a buffer unless the `decodeStrings` option was set to `false`.
-* `encoding` {String} If the chunk is a string, then this is the
-  encoding type.  Ignore chunk is a buffer.  Note that chunk will
-  **always** be a buffer unless the `decodeStrings` option is
-  explicitly set to `false`.
-* `callback` {Function} Call this function (optionally with an error
-  argument) when you are done processing the supplied chunk.
-
-All Writable stream implementations must provide a `_write` method to
-send data to the underlying resource.
-
-Note: **This function MUST NOT be called directly.**  It should be
-implemented by child classes, and called by the internal Writable
-class methods only.
-
-Call the callback using the standard `callback(error)` pattern to
-signal that the write completed successfully or with an error.
-
-If the `decodeStrings` flag is set in the constructor options, then
-`chunk` may be a string rather than a Buffer, and `encoding` will
-indicate the sort of string that it is.  This is to support
-implementations that have an optimized handling for certain string
-data encodings.  If you do not explicitly set the `decodeStrings`
-option to `false`, then you can safely ignore the `encoding` argument,
-and assume that `chunk` will always be a Buffer.
-
-This method is prefixed with an underscore because it is internal to
-the class that defines it, and should not be called directly by user
-programs.  However, you **are** expected to override this method in
-your own extension classes.
-
-
-### writable.write(chunk, [encoding], [callback])
-
-* `chunk` {Buffer | String} Data to be written
-* `encoding` {String} Optional.  If `chunk` is a string, then encoding
-  defaults to `'utf8'`
-* `callback` {Function} Optional.  Called when this chunk is
-  successfully written.
-* Returns {Boolean}
-
-Writes `chunk` to the stream.  Returns `true` if the data has been
-flushed to the underlying resource.  Returns `false` to indicate that
-the buffer is full, and the data will be sent out in the future. The
-`'drain'` event will indicate when the buffer is empty again.
-
-The specifics of when `write()` will return false, is determined by
-the `highWaterMark` option provided to the constructor.
-
-### writable.end([chunk], [encoding], [callback])
-
-* `chunk` {Buffer | String} Optional final data to be written
-* `encoding` {String} Optional.  If `chunk` is a string, then encoding
-  defaults to `'utf8'`
-* `callback` {Function} Optional.  Called when the final chunk is
-  successfully written.
-
-Call this method to signal the end of the data being written to the
-stream.
-
-### Event: 'drain'
-
-Emitted when the stream's write queue empties and it's safe to write
-without buffering again. Listen for it when `stream.write()` returns
-`false`.
-
-### Event: 'close'
-
-Emitted when the underlying resource (for example, the backing file
-descriptor) has been closed. Not all streams will emit this.
-
-### Event: 'finish'
-
-When `end()` is called and there are no more chunks to write, this
-event is emitted.
-
-### Event: 'pipe'
-
-* `source` {Readable Stream}
-
-Emitted when the stream is passed to a readable stream's pipe method.
-
-### Event 'unpipe'
-
-* `source` {Readable Stream}
-
-Emitted when a previously established `pipe()` is removed using the
-source Readable stream's `unpipe()` method.
-
-## Class: stream.Duplex
-
-<!--type=class-->
-
-A "duplex" stream is one that is both Readable and Writable, such as a
-TCP socket connection.
-
-Note that `stream.Duplex` is an abstract class designed to be
-extended with an underlying implementation of the `_read(size)`
-and `_write(chunk, encoding, callback)` methods as you would with a Readable or
-Writable stream class.
-
-Since JavaScript doesn't have multiple prototypal inheritance, this
-class prototypally inherits from Readable, and then parasitically from
-Writable.  It is thus up to the user to implement both the lowlevel
-`_read(n)` method as well as the lowlevel `_write(chunk, encoding, cb)` method
-on extension duplex classes.
-
-### new stream.Duplex(options)
-
-* `options` {Object} Passed to both Writable and Readable
-  constructors. Also has the following fields:
-  * `allowHalfOpen` {Boolean} Default=true.  If set to `false`, then
-    the stream will automatically end the readable side when the
-    writable side ends and vice versa.
-
-In classes that extend the Duplex class, make sure to call the
-constructor so that the buffering settings can be properly
-initialized.
-
-## Class: stream.Transform
-
-A "transform" stream is a duplex stream where the output is causally
-connected in some way to the input, such as a zlib stream or a crypto
-stream.
-
-There is no requirement that the output be the same size as the input,
-the same number of chunks, or arrive at the same time.  For example, a
-Hash stream will only ever have a single chunk of output which is
-provided when the input is ended.  A zlib stream will either produce
-much smaller or much larger than its input.
-
-Rather than implement the `_read()` and `_write()` methods, Transform
-classes must implement the `_transform()` method, and may optionally
-also implement the `_flush()` method.  (See below.)
-
-### new stream.Transform([options])
-
-* `options` {Object} Passed to both Writable and Readable
-  constructors.
-
-In classes that extend the Transform class, make sure to call the
-constructor so that the buffering settings can be properly
-initialized.
-
-### transform.\_transform(chunk, encoding, callback)
-
-* `chunk` {Buffer | String} The chunk to be transformed.  Will always
-  be a buffer unless the `decodeStrings` option was set to `false`.
-* `encoding` {String} If the chunk is a string, then this is the
-  encoding type.  (Ignore if `decodeStrings` chunk is a buffer.)
-* `callback` {Function} Call this function (optionally with an error
-  argument) when you are done processing the supplied chunk.
-
-Note: **This function MUST NOT be called directly.**  It should be
-implemented by child classes, and called by the internal Transform
-class methods only.
-
-All Transform stream implementations must provide a `_transform`
-method to accept input and produce output.
-
-`_transform` should do whatever has to be done in this specific
-Transform class, to handle the bytes being written, and pass them off
-to the readable portion of the interface.  Do asynchronous I/O,
-process things, and so on.
-
-Call `transform.push(outputChunk)` 0 or more times to generate output
-from this input chunk, depending on how much data you want to output
-as a result of this chunk.
-
-Call the callback function only when the current chunk is completely
-consumed.  Note that there may or may not be output as a result of any
-particular input chunk.
-
-This method is prefixed with an underscore because it is internal to
-the class that defines it, and should not be called directly by user
-programs.  However, you **are** expected to override this method in
-your own extension classes.
-
-### transform.\_flush(callback)
-
-* `callback` {Function} Call this function (optionally with an error
-  argument) when you are done flushing any remaining data.
-
-Note: **This function MUST NOT be called directly.**  It MAY be implemented
-by child classes, and if so, will be called by the internal Transform
-class methods only.
-
-In some cases, your transform operation may need to emit a bit more
-data at the end of the stream.  For example, a `Zlib` compression
-stream will store up some internal state so that it can optimally
-compress the output.  At the end, however, it needs to do the best it
-can with what is left, so that the data will be complete.
-
-In those cases, you can implement a `_flush` method, which will be
-called at the very end, after all the written data is consumed, but
-before emitting `end` to signal the end of the readable side.  Just
-like with `_transform`, call `transform.push(chunk)` zero or more
-times, as appropriate, and call `callback` when the flush operation is
-complete.
-
-This method is prefixed with an underscore because it is internal to
-the class that defines it, and should not be called directly by user
-programs.  However, you **are** expected to override this method in
-your own extension classes.
-
-### Example: `SimpleProtocol` parser
-
-The example above of a simple protocol parser can be implemented much
-more simply by using the higher level `Transform` stream class.
-
-In this example, rather than providing the input as an argument, it
-would be piped into the parser, which is a more idiomatic Node stream
-approach.
-
-```javascript
-function SimpleProtocol(options) {
-  if (!(this instanceof SimpleProtocol))
-    return new SimpleProtocol(options);
-
-  Transform.call(this, options);
-  this._inBody = false;
-  this._sawFirstCr = false;
-  this._rawHeader = [];
-  this.header = null;
-}
-
-SimpleProtocol.prototype = Object.create(
-  Transform.prototype, { constructor: { value: SimpleProtocol }});
-
-SimpleProtocol.prototype._transform = function(chunk, encoding, done) {
-  if (!this._inBody) {
-    // check if the chunk has a \n\n
-    var split = -1;
-    for (var i = 0; i < chunk.length; i++) {
-      if (chunk[i] === 10) { // '\n'
-        if (this._sawFirstCr) {
-          split = i;
-          break;
-        } else {
-          this._sawFirstCr = true;
-        }
-      } else {
-        this._sawFirstCr = false;
-      }
-    }
-
-    if (split === -1) {
-      // still waiting for the \n\n
-      // stash the chunk, and try again.
-      this._rawHeader.push(chunk);
-    } else {
-      this._inBody = true;
-      var h = chunk.slice(0, split);
-      this._rawHeader.push(h);
-      var header = Buffer.concat(this._rawHeader).toString();
-      try {
-        this.header = JSON.parse(header);
-      } catch (er) {
-        this.emit('error', new Error('invalid simple protocol data'));
-        return;
-      }
-      // and let them know that we are done parsing the header.
-      this.emit('header', this.header);
-
-      // now, because we got some extra data, emit this first.
-      this.push(b);
-    }
-  } else {
-    // from there on, just provide the data to our consumer as-is.
-    this.push(b);
-  }
-  done();
-};
-
-var parser = new SimpleProtocol();
-source.pipe(parser)
-
-// Now parser is a readable stream that will emit 'header'
-// with the parsed header data.
-```
-
-
-## Class: stream.PassThrough
-
-This is a trivial implementation of a `Transform` stream that simply
-passes the input bytes across to the output.  Its purpose is mainly
-for examples and testing, but there are occasionally use cases where
-it can come in handy.

You can use it to have programs that\nhave to work with node v0.8, while being forward-compatible for v0.10\nand beyond.  When you drop support for v0.8, you can remove this\nmodule, and only use the native streams.\n\nThis is almost exactly the same codebase as appears in Node v0.10.\nHowever:\n\n1. The exported object is actually the Readable class.  Decorating the\n   native `stream` module would be global pollution.\n2. In v0.10, you can safely use `base64` as an argument to\n   `setEncoding` in Readable streams.  However, in v0.8, the\n   StringDecoder class has no `end()` method, which is problematic for\n   Base64.  So, don't use that, because it'll break and be weird.\n\nOther than that, the API is the same as `require('stream')` in v0.10,\nso the API docs are reproduced below.\n\n----------\n\n    Stability: 2 - Unstable\n\nA stream is an abstract interface implemented by various objects in\nNode.  For example a request to an HTTP server is a stream, as is\nstdout. Streams are readable, writable, or both. All streams are\ninstances of [EventEmitter][]\n\nYou can load the Stream base classes by doing `require('stream')`.\nThere are base classes provided for Readable streams, Writable\nstreams, Duplex streams, and Transform streams.\n\n## Compatibility\n\nIn earlier versions of Node, the Readable stream interface was\nsimpler, but also less powerful and less useful.\n\n* Rather than waiting for you to call the `read()` method, `'data'`\n  events would start emitting immediately.  If you needed to do some\n  I/O to decide how to handle data, then you had to store the chunks\n  in some kind of buffer so that they would not be lost.\n* The `pause()` method was advisory, rather than guaranteed.  This\n  meant that you still had to be prepared to receive `'data'` events\n  even when the stream was in a paused state.\n\nIn Node v0.10, the Readable class described below was added.  For\nbackwards compatibility with older Node programs, Readable streams\nswitch into \"old mode\" when a `'data'` event handler is added, or when\nthe `pause()` or `resume()` methods are called.  The effect is that,\neven if you are not using the new `read()` method and `'readable'`\nevent, you no longer have to worry about losing `'data'` chunks.\n\nMost programs will continue to function normally.  However, this\nintroduces an edge case in the following conditions:\n\n* No `'data'` event handler is added.\n* The `pause()` and `resume()` methods are never called.\n\nFor example, consider the following code:\n\n```javascript\n// WARNING!  BROKEN!\nnet.createServer(function(socket) {\n\n  // we add an 'end' method, but never consume the data\n  socket.on('end', function() {\n    // It will never get here.\n    socket.end('I got your message (but didnt read it)\\n');\n  });\n\n}).listen(1337);\n```\n\nIn versions of node prior to v0.10, the incoming message data would be\nsimply discarded.  However, in Node v0.10 and beyond, the socket will\nremain paused forever.\n\nThe workaround in this situation is to call the `resume()` method to\ntrigger \"old mode\" behavior:\n\n```javascript\n// Workaround\nnet.createServer(function(socket) {\n\n  socket.on('end', function() {\n    socket.end('I got your message (but didnt read it)\\n');\n  });\n\n  // start the flow of data, discarding it.\n  socket.resume();\n\n}).listen(1337);\n```\n\nIn addition to new Readable streams switching into old-mode, pre-v0.10\nstyle streams can be wrapped in a Readable class using the `wrap()`\nmethod.\n\n## Class: stream.Readable\n\n<!--type=class-->\n\nA `Readable Stream` has the following methods, members, and events.\n\nNote that `stream.Readable` is an abstract class designed to be\nextended with an underlying implementation of the `_read(size)`\nmethod. (See below.)\n\n### new stream.Readable([options])\n\n* `options` {Object}\n  * `highWaterMark` {Number} The maximum number of bytes to store in\n    the internal buffer before ceasing to read from the underlying\n    resource.  Default=16kb\n  * `encoding` {String} If specified, then buffers will be decoded to\n    strings using the specified encoding.  Default=null\n  * `objectMode` {Boolean} Whether this stream should behave\n    as a stream of objects. Meaning that stream.read(n) returns\n    a single value instead of a Buffer of size n\n\nIn classes that extend the Readable class, make sure to call the\nconstructor so that the buffering settings can be properly\ninitialized.\n\n### readable.\\_read(size)\n\n* `size` {Number} Number of bytes to read asynchronously\n\nNote: **This function should NOT be called directly.**  It should be\nimplemented by child classes, and called by the internal Readable\nclass methods only.\n\nAll Readable stream implementations must provide a `_read` method\nto fetch data from the underlying resource.\n\nThis method is prefixed with an underscore because it is internal to\nthe class that defines it, and should not be called directly by user\nprograms.  However, you **are** expected to override this method in\nyour own extension classes.\n\nWhen data is available, put it into the read queue by calling\n`readable.push(chunk)`.  If `push` returns false, then you should stop\nreading.  When `_read` is called again, you should start pushing more\ndata.\n\nThe `size` argument is advisory.  Implementations where a \"read\" is a\nsingle call that returns data can use this to know how much data to\nfetch.  Implementations where that is not relevant, such as TCP or\nTLS, may ignore this argument, and simply provide data whenever it\nbecomes available.  There is no need, for example to \"wait\" until\n`size` bytes are available before calling `stream.push(chunk)`.\n\n### readable.push(chunk)\n\n* `chunk` {Buffer | null | String} Chunk of data to push into the read queue\n* return {Boolean} Whether or not more pushes should be performed\n\nNote: **This function should be called by Readable implementors, NOT\nby consumers of Readable subclasses.**  The `_read()` function will not\nbe called again until at least one `push(chunk)` call is made.  If no\ndata is available, then you MAY call `push('')` (an empty string) to\nallow a future `_read` call, without adding any data to the queue.\n\nThe `Readable` class works by putting data into a read queue to be\npulled out later by calling the `read()` method when the `'readable'`\nevent fires.\n\nThe `push()` method will explicitly insert some data into the read\nqueue.  If it is called with `null` then it will signal the end of the\ndata.\n\nIn some cases, you may be wrapping a lower-level source which has some\nsort of pause/resume mechanism, and a data callback.  In those cases,\nyou could wrap the low-level source object by doing something like\nthis:\n\n```javascript\n// source is an object with readStop() and readStart() methods,\n// and an `ondata` member that gets called when it has data, and\n// an `onend` member that gets called when the data is over.\n\nvar stream = new Readable();\n\nsource.ondata = function(chunk) {\n  // if push() returns false, then we need to stop reading from source\n  if (!stream.push(chunk))\n    source.readStop();\n};\n\nsource.onend = function() {\n  stream.push(null);\n};\n\n// _read will be called when the stream wants to pull more data in\n// the advisory size argument is ignored in this case.\nstream._read = function(n) {\n  source.readStart();\n};\n```\n\n### readable.unshift(chunk)\n\n* `chunk` {Buffer | null | String} Chunk of data to unshift onto the read queue\n* return {Boolean} Whether or not more pushes should be performed\n\nThis is the corollary of `readable.push(chunk)`.  Rather than putting\nthe data at the *end* of the read queue, it puts it at the *front* of\nthe read queue.\n\nThis is useful in certain use-cases where a stream is being consumed\nby a parser, which needs to \"un-consume\" some data that it has\noptimistically pulled out of the source.\n\n```javascript\n// A parser for a simple data protocol.\n// The \"header\" is a JSON object, followed by 2 \\n characters, and\n// then a message body.\n//\n// Note: This can be done more simply as a Transform stream.  See below.\n\nfunction SimpleProtocol(source, options) {\n  if (!(this instanceof SimpleProtocol))\n    return new SimpleProtocol(options);\n\n  Readable.call(this, options);\n  this._inBody = false;\n  this._sawFirstCr = false;\n\n  // source is a readable stream, such as a socket or file\n  this._source = source;\n\n  var self = this;\n  source.on('end', function() {\n    self.push(null);\n  });\n\n  // give it a kick whenever the source is readable\n  // read(0) will not consume any bytes\n  source.on('readable', function() {\n    self.read(0);\n  });\n\n  this._rawHeader = [];\n  this.header = null;\n}\n\nSimpleProtocol.prototype = Object.create(\n  Readable.prototype, { constructor: { value: SimpleProtocol }});\n\nSimpleProtocol.prototype._read = function(n) {\n  if (!this._inBody) {\n    var chunk = this._source.read();\n\n    // if the source doesn't have data, we don't have data yet.\n    if (chunk === null)\n      return this.push('');\n\n    // check if the chunk has a \\n\\n\n    var split = -1;\n    for (var i = 0; i < chunk.length; i++) {\n      if (chunk[i] === 10) { // '\\n'\n        if (this._sawFirstCr) {\n          split = i;\n          break;\n        } else {\n          this._sawFirstCr = true;\n        }\n      } else {\n        this._sawFirstCr = false;\n      }\n    }\n\n    if (split === -1) {\n      // still waiting for the \\n\\n\n      // stash the chunk, and try again.\n      this._rawHeader.push(chunk);\n      this.push('');\n    } else {\n      this._inBody = true;\n      var h = chunk.slice(0, split);\n      this._rawHeader.push(h);\n      var header = Buffer.concat(this._rawHeader).toString();\n      try {\n        this.header = JSON.parse(header);\n      } catch (er) {\n        this.emit('error', new Error('invalid simple protocol data'));\n        return;\n      }\n      // now, because we got some extra data, unshift the rest\n      // back into the read queue so that our consumer will see it.\n      var b = chunk.slice(split);\n      this.unshift(b);\n\n      // and let them know that we are done parsing the header.\n      this.emit('header', this.header);\n    }\n  } else {\n    // from there on, just provide the data to our consumer.\n    // careful not to push(null), since that would indicate EOF.\n    var chunk = this._source.read();\n    if (chunk) this.push(chunk);\n  }\n};\n\n// Usage:\nvar parser = new SimpleProtocol(source);\n// Now parser is a readable stream that will emit 'header'\n// with the parsed header data.\n```\n\n### readable.wrap(stream)\n\n* `stream` {Stream} An \"old style\" readable stream\n\nIf you are using an older Node library that emits `'data'` events and\nhas a `pause()` method that is advisory only, then you can use the\n`wrap()` method to create a Readable stream that uses the old stream\nas its data source.\n\nFor example:\n\n```javascript\nvar OldReader = require('./old-api-module.js').OldReader;\nvar oreader = new OldReader;\nvar Readable = require('stream').Readable;\nvar myReader = new Readable().wrap(oreader);\n\nmyReader.on('readable', function() {\n  myReader.read(); // etc.\n});\n```\n\n### Event: 'readable'\n\nWhen there is data ready to be consumed, this event will fire.\n\nWhen this event emits, call the `read()` method to consume the data.\n\n### Event: 'end'\n\nEmitted when the stream has received an EOF (FIN in TCP terminology).\nIndicates that no more `'data'` events will happen. If the stream is\nalso writable, it may be possible to continue writing.\n\n### Event: 'data'\n\nThe `'data'` event emits either a `Buffer` (by default) or a string if\n`setEncoding()` was used.\n\nNote that adding a `'data'` event listener will switch the Readable\nstream into \"old mode\", where data is emitted as soon as it is\navailable, rather than waiting for you to call `read()` to consume it.\n\n### Event: 'error'\n\nEmitted if there was an error receiving data.\n\n### Event: 'close'\n\nEmitted when the underlying resource (for example, the backing file\ndescriptor) has been closed. Not all streams will emit this.\n\n### readable.setEncoding(encoding)\n\nMakes the `'data'` event emit a string instead of a `Buffer`. `encoding`\ncan be `'utf8'`, `'utf16le'` (`'ucs2'`), `'ascii'`, or `'hex'`.\n\nThe encoding can also be set by specifying an `encoding` field to the\nconstructor.\n\n### readable.read([size])\n\n* `size` {Number | null} Optional number of bytes to read.\n* Return: {Buffer | String | null}\n\nNote: **This function SHOULD be called by Readable stream users.**\n\nCall this method to consume data once the `'readable'` event is\nemitted.\n\nThe `size` argument will set a minimum number of bytes that you are\ninterested in.  If not set, then the entire content of the internal\nbuffer is returned.\n\nIf there is no data to consume, or if there are fewer bytes in the\ninternal buffer than the `size` argument, then `null` is returned, and\na future `'readable'` event will be emitted when more is available.\n\nCalling `stream.read(0)` will always return `null`, and will trigger a\nrefresh of the internal buffer, but otherwise be a no-op.\n\n### readable.pipe(destination, [options])\n\n* `destination` {Writable Stream}\n* `options` {Object} Optional\n  * `end` {Boolean} Default=true\n\nConnects this readable stream to `destination` WriteStream. Incoming\ndata on this stream gets written to `destination`.  Properly manages\nback-pressure so that a slow destination will not be overwhelmed by a\nfast readable stream.\n\nThis function returns the `destination` stream.\n\nFor example, emulating the Unix `cat` command:\n\n    process.stdin.pipe(process.stdout);\n\nBy default `end()` is called on the destination when the source stream\nemits `end`, so that `destination` is no longer writable. Pass `{ end:\nfalse }` as `options` to keep the destination stream open.\n\nThis keeps `writer` open so that \"Goodbye\" can be written at the\nend.\n\n    reader.pipe(writer, { end: false });\n    reader.on(\"end\", function() {\n      writer.end(\"Goodbye\\n\");\n    });\n\nNote that `process.stderr` and `process.stdout` are never closed until\nthe process exits, regardless of the specified options.\n\n### readable.unpipe([destination])\n\n* `destination` {Writable Stream} Optional\n\nUndo a previously established `pipe()`.  If no destination is\nprovided, then all previously established pipes are removed.\n\n### readable.pause()\n\nSwitches the readable stream into \"old mode\", where data is emitted\nusing a `'data'` event rather than being buffered for consumption via\nthe `read()` method.\n\nCeases the flow of data.  No `'data'` events are emitted while the\nstream is in a paused state.\n\n### readable.resume()\n\nSwitches the readable stream into \"old mode\", where data is emitted\nusing a `'data'` event rather than being buffered for consumption via\nthe `read()` method.\n\nResumes the incoming `'data'` events after a `pause()`.\n\n\n## Class: stream.Writable\n\n<!--type=class-->\n\nA `Writable` Stream has the following methods, members, and events.\n\nNote that `stream.Writable` is an abstract class designed to be\nextended with an underlying implementation of the\n`_write(chunk, encoding, cb)` method. (See below.)\n\n### new stream.Writable([options])\n\n* `options` {Object}\n  * `highWaterMark` {Number} Buffer level when `write()` starts\n    returning false. Default=16kb\n  * `decodeStrings` {Boolean} Whether or not to decode strings into\n    Buffers before passing them to `_write()`.  Default=true\n\nIn classes that extend the Writable class, make sure to call the\nconstructor so that the buffering settings can be properly\ninitialized.\n\n### writable.\\_write(chunk, encoding, callback)\n\n* `chunk` {Buffer | String} The chunk to be written.  Will always\n  be a buffer unless the `decodeStrings` option was set to `false`.\n* `encoding` {String} If the chunk is a string, then this is the\n  encoding type.  Ignore chunk is a buffer.  Note that chunk will\n  **always** be a buffer unless the `decodeStrings` option is\n  explicitly set to `false`.\n* `callback` {Function} Call this function (optionally with an error\n  argument) when you are done processing the supplied chunk.\n\nAll Writable stream implementations must provide a `_write` method to\nsend data to the underlying resource.\n\nNote: **This function MUST NOT be called directly.**  It should be\nimplemented by child classes, and called by the internal Writable\nclass methods only.\n\nCall the callback using the standard `callback(error)` pattern to\nsignal that the write completed successfully or with an error.\n\nIf the `decodeStrings` flag is set in the constructor options, then\n`chunk` may be a string rather than a Buffer, and `encoding` will\nindicate the sort of string that it is.  This is to support\nimplementations that have an optimized handling for certain string\ndata encodings.  If you do not explicitly set the `decodeStrings`\noption to `false`, then you can safely ignore the `encoding` argument,\nand assume that `chunk` will always be a Buffer.\n\nThis method is prefixed with an underscore because it is internal to\nthe class that defines it, and should not be called directly by user\nprograms.  However, you **are** expected to override this method in\nyour own extension classes.\n\n\n### writable.write(chunk, [encoding], [callback])\n\n* `chunk` {Buffer | String} Data to be written\n* `encoding` {String} Optional.  If `chunk` is a string, then encoding\n  defaults to `'utf8'`\n* `callback` {Function} Optional.  Called when this chunk is\n  successfully written.\n* Returns {Boolean}\n\nWrites `chunk` to the stream.  Returns `true` if the data has been\nflushed to the underlying resource.  Returns `false` to indicate that\nthe buffer is full, and the data will be sent out in the future. The\n`'drain'` event will indicate when the buffer is empty again.\n\nThe specifics of when `write()` will return false, is determined by\nthe `highWaterMark` option provided to the constructor.\n\n### writable.end([chunk], [encoding], [callback])\n\n* `chunk` {Buffer | String} Optional final data to be written\n* `encoding` {String} Optional.  If `chunk` is a string, then encoding\n  defaults to `'utf8'`\n* `callback` {Function} Optional.  Called when the final chunk is\n  successfully written.\n\nCall this method to signal the end of the data being written to the\nstream.\n\n### Event: 'drain'\n\nEmitted when the stream's write queue empties and it's safe to write\nwithout buffering again. Listen for it when `stream.write()` returns\n`false`.\n\n### Event: 'close'\n\nEmitted when the underlying resource (for example, the backing file\ndescriptor) has been closed. Not all streams will emit this.\n\n### Event: 'finish'\n\nWhen `end()` is called and there are no more chunks to write, this\nevent is emitted.\n\n### Event: 'pipe'\n\n* `source` {Readable Stream}\n\nEmitted when the stream is passed to a readable stream's pipe method.\n\n### Event 'unpipe'\n\n* `source` {Readable Stream}\n\nEmitted when a previously established `pipe()` is removed using the\nsource Readable stream's `unpipe()` method.\n\n## Class: stream.Duplex\n\n<!--type=class-->\n\nA \"duplex\" stream is one that is both Readable and Writable, such as a\nTCP socket connection.\n\nNote that `stream.Duplex` is an abstract class designed to be\nextended with an underlying implementation of the `_read(size)`\nand `_write(chunk, encoding, callback)` methods as you would with a Readable or\nWritable stream class.\n\nSince JavaScript doesn't have multiple prototypal inheritance, this\nclass prototypally inherits from Readable, and then parasitically from\nWritable.  It is thus up to the user to implement both the lowlevel\n`_read(n)` method as well as the lowlevel `_write(chunk, encoding, cb)` method\non extension duplex classes.\n\n### new stream.Duplex(options)\n\n* `options` {Object} Passed to both Writable and Readable\n  constructors. Also has the following fields:\n  * `allowHalfOpen` {Boolean} Default=true.  If set to `false`, then\n    the stream will automatically end the readable side when the\n    writable side ends and vice versa.\n\nIn classes that extend the Duplex class, make sure to call the\nconstructor so that the buffering settings can be properly\ninitialized.\n\n## Class: stream.Transform\n\nA \"transform\" stream is a duplex stream where the output is causally\nconnected in some way to the input, such as a zlib stream or a crypto\nstream.\n\nThere is no requirement that the output be the same size as the input,\nthe same number of chunks, or arrive at the same time.  For example, a\nHash stream will only ever have a single chunk of output which is\nprovided when the input is ended.  A zlib stream will either produce\nmuch smaller or much larger than its input.\n\nRather than implement the `_read()` and `_write()` methods, Transform\nclasses must implement the `_transform()` method, and may optionally\nalso implement the `_flush()` method.  (See below.)\n\n### new stream.Transform([options])\n\n* `options` {Object} Passed to both Writable and Readable\n  constructors.\n\nIn classes that extend the Transform class, make sure to call the\nconstructor so that the buffering settings can be properly\ninitialized.\n\n### transform.\\_transform(chunk, encoding, callback)\n\n* `chunk` {Buffer | String} The chunk to be transformed.  Will always\n  be a buffer unless the `decodeStrings` option was set to `false`.\n* `encoding` {String} If the chunk is a string, then this is the\n  encoding type.  (Ignore if `decodeStrings` chunk is a buffer.)\n* `callback` {Function} Call this function (optionally with an error\n  argument) when you are done processing the supplied chunk.\n\nNote: **This function MUST NOT be called directly.**  It should be\nimplemented by child classes, and called by the internal Transform\nclass methods only.\n\nAll Transform stream implementations must provide a `_transform`\nmethod to accept input and produce output.\n\n`_transform` should do whatever has to be done in this specific\nTransform class, to handle the bytes being written, and pass them off\nto the readable portion of the interface.  Do asynchronous I/O,\nprocess things, and so on.\n\nCall `transform.push(outputChunk)` 0 or more times to generate output\nfrom this input chunk, depending on how much data you want to output\nas a result of this chunk.\n\nCall the callback function only when the current chunk is completely\nconsumed.  Note that there may or may not be output as a result of any\nparticular input chunk.\n\nThis method is prefixed with an underscore because it is internal to\nthe class that defines it, and should not be called directly by user\nprograms.  However, you **are** expected to override this method in\nyour own extension classes.\n\n### transform.\\_flush(callback)\n\n* `callback` {Function} Call this function (optionally with an error\n  argument) when you are done flushing any remaining data.\n\nNote: **This function MUST NOT be called directly.**  It MAY be implemented\nby child classes, and if so, will be called by the internal Transform\nclass methods only.\n\nIn some cases, your transform operation may need to emit a bit more\ndata at the end of the stream.  For example, a `Zlib` compression\nstream will store up some internal state so that it can optimally\ncompress the output.  At the end, however, it needs to do the best it\ncan with what is left, so that the data will be complete.\n\nIn those cases, you can implement a `_flush` method, which will be\ncalled at the very end, after all the written data is consumed, but\nbefore emitting `end` to signal the end of the readable side.  Just\nlike with `_transform`, call `transform.push(chunk)` zero or more\ntimes, as appropriate, and call `callback` when the flush operation is\ncomplete.\n\nThis method is prefixed with an underscore because it is internal to\nthe class that defines it, and should not be called directly by user\nprograms.  However, you **are** expected to override this method in\nyour own extension classes.\n\n### Example: `SimpleProtocol` parser\n\nThe example above of a simple protocol parser can be implemented much\nmore simply by using the higher level `Transform` stream class.\n\nIn this example, rather than providing the input as an argument, it\nwould be piped into the parser, which is a more idiomatic Node stream\napproach.\n\n```javascript\nfunction SimpleProtocol(options) {\n  if (!(this instanceof SimpleProtocol))\n    return new SimpleProtocol(options);\n\n  Transform.call(this, options);\n  this._inBody = false;\n  this._sawFirstCr = false;\n  this._rawHeader = [];\n  this.header = null;\n}\n\nSimpleProtocol.prototype = Object.create(\n  Transform.prototype, { constructor: { value: SimpleProtocol }});\n\nSimpleProtocol.prototype._transform = function(chunk, encoding, done) {\n  if (!this._inBody) {\n    // check if the chunk has a \\n\\n\n    var split = -1;\n    for (var i = 0; i < chunk.length; i++) {\n      if (chunk[i] === 10) { // '\\n'\n        if (this._sawFirstCr) {\n          split = i;\n          break;\n        } else {\n          this._sawFirstCr = true;\n        }\n      } else {\n        this._sawFirstCr = false;\n      }\n    }\n\n    if (split === -1) {\n      // still waiting for the \\n\\n\n      // stash the chunk, and try again.\n      this._rawHeader.push(chunk);\n    } else {\n      this._inBody = true;\n      var h = chunk.slice(0, split);\n      this._rawHeader.push(h);\n      var header = Buffer.concat(this._rawHeader).toString();\n      try {\n        this.header = JSON.parse(header);\n      } catch (er) {\n        this.emit('error', new Error('invalid simple protocol data'));\n        return;\n      }\n      // and let them know that we are done parsing the header.\n      this.emit('header', this.header);\n\n      // now, because we got some extra data, emit this first.\n      this.push(b);\n    }\n  } else {\n    // from there on, just provide the data to our consumer as-is.\n    this.push(b);\n  }\n  done();\n};\n\nvar parser = new SimpleProtocol();\nsource.pipe(parser)\n\n// Now parser is a readable stream that will emit 'header'\n// with the parsed header data.\n```\n\n\n## Class: stream.PassThrough\n\nThis is a trivial implementation of a `Transform` stream that simply\npasses the input bytes across to the output.  Its purpose is mainly\nfor examples and testing, but there are occasionally use cases where\nit can come in handy.\n\n\n[EventEmitter]: events.html#events_class_events_eventemitter\n",

The former tracks the Streams2 implementation in Node 0.10, including bug-fixes and minor improvements as they are added. The latter tracks Streams3 as it develops in Node 0.11; we will likely see a v1.2.x branch for Node 0.12.\n\n**readable-stream** uses proper patch-level versioning so if you pin to `\"~1.0.0\"` you’ll get the latest Node 0.10 Streams2 implementation, including any fixes and minor non-breaking improvements. The patch-level versions of 1.0.x and 1.1.x should mirror the patch-level versions of Node-core releases.

-- More logging
-- Prettier time durations
-- Tons of documentation changes
-- gulp.trigger(tasks...) as a through stream
-
-## 1.2-2.4 (11/12/13)
-
-- src buffer=false fixed for 0.8 and 0.9 (remember to .resume() on these versions before consuming)
-- CLI completely rewritten
-  - Colorful logging
-  - Uses local version of gulp to run tasks
-  - Uses findup to locate gulpfile (so you can run it anywhere in your project)
-  - chdir to gulpfile directory before loading it
-  - Correct exit codes on errors
-- silent flag added to gulp to disable logging
-- Fixes to task orchestration (3rd party)
-- Better support for globbed directories (thanks @robrich)
-
-## 1.2 (10/28/13)
-
-- Can specify buffer=false on src streams to make file.content a stream
-- Can specify read=false on src streams to disable file.content
-
-## 1.1 (10/21/13)
-
-- Can specify run callback
-- Can specify task dependencies
-- Tasks can accept callback or return promise
-- `gulp.verbose` exposes run-time internals
-
-## 1.0 (9/26/13)
-
-- Specify dependency versions
-- Updated docs
-
-## 0.2 (8/6/13)
-
-- Rename .files() to .src() and .folder() to .dest()
-
-## 0.1 (7/18/13)
-
-- Initial Release

-## gulp API docs
-
-### gulp.src(globs[, options])
-
-Takes a glob and represents a file structure. Can be piped to plugins.
-
-```javascript
-gulp.src('./client/templates/*.jade')
-    .pipe(jade())
-    .pipe(minify())
-    .pipe(gulp.dest('./build/minified_templates'));
-```
-
-#### globs
-Type: `String` or `Array`
-
-Glob or globs to read.
-
-#### options
-Type: `Object`
-
-Options to pass to [node-glob] through [glob-stream].
-
-gulp adds two additional options in addition to the [options supported by node-glob][node-glob documentation]:
-
-#### options.buffer
-Type: `Boolean`
-Default: `true`
-
-Setting this to `false` will return `file.contents` as a stream and not buffer files. This is useful when working with large files. **Note:** Plugins may not implement support for streams.
-
-#### options.read
-Type: `Boolean`
-Default: `true`
-
-Setting this to `false` will return `file.contents` as null and not read the file at all.
-
-
-### gulp.dest(path)
-
-Can be piped to and it will write files. Re-emits all data passed to it so you can pipe to multiple folders.
-
-```javascript
-gulp.src('./client/templates/*.jade')
-  .pipe(jade())
-  .pipe(gulp.dest('./build/templates'))
-  .pipe(minify())
-  .pipe(gulp.dest('./build/minified_templates'));
-```
-
-#### path
-Type: `String`
-
-The path (folder) to write files to.
-
-
-### gulp.task(name[, deps], fn)
-
-Define a task using [Orchestrator].
-
-```javascript
-gulp.task('somename', function() {
-  // Do stuff
-});
-```
-
-#### name
-
-The name of the task. Tasks that you want to run from the command line should not have spaces in them.
-
-#### deps
-Type: `Array`
-
-An array of tasks to be executed and completed before your task will run.
-
-```javascript
-gulp.task('mytask', ['array', 'of', 'task', 'names'], function() {
-  // Do stuff
-});
-```
-
-**Note:** Are your tasks running before the dependencies are complete?  Make sure your dependency tasks
-are correctly using the async run hints: take in a callback or return a promise or event stream.
-
-#### fn
-
-The function that performs the task's operations. Generally this takes the form of `gulp.src().pipe(someplugin())`.
-
-#### Async task support
-
-Tasks can be made asynchronous if its `fn` does one of the following:
-
-##### Accept a callback
-
-```javascript
-gulp.task('somename', function(cb) {
-  // Do stuff
-  cb(err);
-});
-```
-
-##### Return a stream
-
-```javascript
-gulp.task('somename', function() {
-  var stream = gulp.src('./client/**/*.js')
-    .pipe(minify())
-    .pipe(gulp.dest('/build'));
-  return stream;
-});
-```
-
-##### Return a promise
-
-```javascript
-var Q = require('q');
-
-gulp.task('somename', function() {
-  var deferred = Q.defer();
-
-  // Do async stuff
-  setTimeout(function() {
-    deferred.resolve();
-  }, 1);
-
-  return deferred.promise;
-});
-```
-
-**Note:** By default, tasks run with maximum concurrency -- e.g. it launches all the tasks at once and waits for nothing.
-If you want to create a series where tasks run in a particular order, you need to do two things:
-
-- give it a hint to tell it when the task is done,
-- and give it a hint that a task depends on completion of another.
-
-For these examples, let's presume you have two tasks, "one" and "two" that you specifically want to run in this order:
-
-1. In task "one" you add a hint to tell it when the task is done.  Either take in a callback and call it when you're
-done or return a promise or stream that the engine should wait to resolve or end respectively.
-
-2. In task "two" you add a hint telling the engine that it depends on completion of the first task.
-
-So this example would look like this:
-
-```javascript
-var gulp = require('gulp');
-
-// takes in a callback so the engine knows when it'll be done
-gulp.task('one', function (cb) {
-    // do stuff -- async or otherwise
-    cb(err); // if err is not null and not undefined, the run will stop, and note that it failed
-});
-
-// identifies a dependent task must be complete before this one begins
-gulp.task('two', ['one'], function () {
-    // task 'one' is done now
-});
-
-gulp.task('default', ['one', 'two']);
-```
-
-
-### gulp.watch(glob [, opts], tasks) or gulp.watch(glob [, opts, cb])
-
-Watch files and do something when a file changes. This always returns an EventEmitter that emits `changed` events.
-
-### gulp.watch(glob[, opts], tasks)
-
-#### glob
-Type: `String` or `Array`
-
-A single glob or array of globs that indicate which files to watch for changes.
-
-#### opts
-Type: `Object`
-
-Options, that are passed to [`gaze`](https://github.com/shama/gaze).
-
-#### tasks
-Type: `Array`
-
-Names of task(s) to run when a file changes, added with `gulp.task()`
-
-```javascript
-var watcher = gulp.watch('js/**/*.js', ['uglify','reload']);
-watcher.on('changed', function(event){
-  console.log('File '+event.path+' was '+event.type+', running tasks...');
-});
-```
-
-### gulp.watch(glob[, opts, cb])
-
-#### glob
-Type: `String` or `Array`
-
-A single glob or array of globs that indicate which files to watch for changes.
-
-#### opts
-Type: `Object`
-
-Options, that are passed to [`gaze`](https://github.com/shama/gaze).
-
-#### cb(event)
-Type: `Function`
-
-Callback to be called on each change.
-
-```javascript
-gulp.watch('js/**/*.js', function(event) {
-  console.log('File '+event.path+' was '+event.type+', running tasks...');
-});
-```
-
-The callback will be passed an object, `event`, that describes the change:
-
-##### event.type
-Type: `String`
-
-The type of change that occurred, either `added`, `changed` or `deleted`.
-
-##### event.path
-Type: `String`
-
-The path to the file that triggered the event.

-## gulp CLI docs
-
-### Flags
-
-gulp has very few flags to know about. All other flags are for tasks to use if needed.
-
-- `-V` or `--version` will display the global and local gulp versions
-- `--require <module path>` will require a module before running the gulpfile. This is useful for transpilers but also has other applications. You can use multiple `--require` flags
-- `--gulpfile <gulpfile path>` manually set path of gulpfile. Useful if you have multiple gulpfiles. This will set the CWD to the gulpfile directory as well.
-- `--cwd <dir path>` manually set the CWD. The search for the gulpfile, as well as the relativity of all requires will be from here.
-- `-T` or `--tasks` will display the task dependency tree for the loaded gulpfile
-
-### Tasks
-
-Tasks can be executed by running `gulp <task> <othertask>`. Just running `gulp` will execute the task you registered called `default`. If there is no `default` task gulp will error.
-
-### Compilers
-
-You can use any language you want for your gulpfile. You will have to specify the language module name so the CLI can load it (and its associated extensions) before attempting to find your gulpfile. Make sure you have this module installed accessible by the folder you are running the CLI in.
-
-Example:
-
-```
-gulp dosomething --require coffee-script/register
-```

-# FAQ
-
-## Why gulp? Why not ____?
-
-See the [gulp introduction slideshow] for a rundown on how gulp came to be.
-
-## Is it "gulp" or "Gulp"?
-
-gulp is always lowercase.
-
-## Where can I find a list of gulp plugins?
-
-gulp plugins always include the `gulpplugin` keyword. [Search gulp plugins][search-gulp-plugins] or [view all plugins][npm plugin search].
-
-## I want to write a gulp plugin, how do I get started?
-
-See the [Writing a gulp plugin] wiki page for guidelines and an example to get you started.
-
-## My plugin does ____, is it doing too much?
-
-Probably. Ask yourself:
-
-1. Is my plugin doing something that other plugins may need to do?
-  - If so, that piece of functionality should be a separate plugin. [Check if it already exists on npm][npm plugin search].
-1. Is my plugin doing two, completely different things based on a configuration option?
-  - If so, it may serve the community better to release it as two separate plugins
-  - If the two tasks are different, but very closely related, it's probably OK
-
-## How should newlines be represented in plugin output?
-
-Always use gulp-util.newline (which is \n) to prevent diff issues between operating systems.
-
-## Where can I get updates on gulp?
-
-gulp updates can be found on the following twitters:
-
-- [@wearefractal](https://twitter.com/wearefractal)
-- [@eschoff](https://twitter.com/eschoff)
-- [@funkytek](https://twitter.com/funkytek)
-- [@gulpjs](https://twitter.com/gulpjs)
-
-## Does gulp have an IRC channel?
-
-Yes, come chat with us in #gulpjs on [Freenode].

-## Getting Started
-
-### 1. Install gulp globally:
-
-```
-npm install -g gulp
-```
-
-### 2. Install gulp and gulp-util in your project devDependencies:
-
-```
-npm install --save-dev gulp gulp-util
-```
-
-### 3. Create a `gulpfile.js` at the root of your project:
-
-```javascript
-var gulp = require('gulp');
-var gutil = require('gulp-util');
-
-gulp.task('default', function(){
-  // place code for your default task here
-});
-```
-
-### 4. Run gulp
-
-```
-gulp
-```
-
-The default task will run and do nothing.
-
-To run individual tasks, use `gulp <task> <othertask>`
-
-## Where do I go now?
-
-You have an empty gulpfile and everything is installed. How do you REALLY get started? Check out the [recipes and articles section](README.md#articles-and-recipes) for more information
-
-## .src, .watch, .dest, CLI args - How do I use these things?
-
-For API specific documentation you can check out the [documentation for that](API.md)
-
-## Available Plugins
-
-The gulp community is growing, with new plugins being added daily. See the [main website](http://gulpjs.com/) for a complete list.

-# Combining streams to handle errors #
-
-By default, emitting an error on a stream will cause it to be thrown
-unless it already has a listener attached to the `error` event. This
-gets a bit tricky when you're working with longer pipelines of streams.
-
-By using [gulp-util](https://github.com/gulpjs/gulp-util)'s `combine`
-method you can turn a series of streams into a single stream, meaning you
-only need to listen to the `error` event in one place in your code.
-
-Here's an example of using it in a gulpfile:
-
-``` javascript
-var combine = require('gulp-util').combine
-var uglify = require('gulp-uglify')
-var gulp = require('gulp')
-
-gulp.task('test', function() {
-  var combined = combine(
-    gulp.src('bootstrap/js/*.js'),
-    uglify(),
-    gulp.dest('public/bootstrap')
-  )
-
-  // any errors in the above streams
-  // will get caught by this listener,
-  // instead of being thrown:
-  combined.on('error', function(err) {
-    console.warn(err.message)
-  })
-
-  return combined
-})
-```
-
-You can use this technique in your gulp plugins and node modules too using
-the [multipipe](http://npmjs.org/package/multipipe) module, and is a generally useful means of ensuring that errors aren't thrown from inaccessible streams
-somewhere deep inside `./node_modules`.

-# Running tasks in series
-
-By default, tasks run with maximum concurrency -- e.g. it launches all the tasks at once and waits for nothing.
-If you want to create a series where tasks run in a particular order, you need to do two things:
-
-- give it a hint to tell it when the task is done,
-- and give it a hint that a task depends on completion of another.
-
-For these examples, let's presume you have two tasks, "one" and "two" that you specifically want to run in this order:
-
-1. In task "one" you add a hint to tell it when the task is done.  Either take in a callback and call it when you're
-done or return a promise or stream that the engine should wait to resolve or end respectively.
-
-2. In task "two" you add a hint telling the engine that it depends on completion of the first task.
-
-So this example would look like this:
-
-```javascript
-var gulp = require('gulp');
-
-// takes in a callback so the engine knows when it'll be done
-gulp.task('one', function (cb) {
-    // do stuff -- async or otherwise
-    cb(err); // if err is not null and not undefined, the orchestration will stop, and 'two' will not run
-});
-
-// identifies a dependent task must be complete before this one begins
-gulp.task('two', ['one'], function () {
-    // task 'one' is done now
-});
-
-gulp.task('default', ['one', 'two']);
-// alternatively: gulp.task('default', ['two']);
-```

-# Writing a plugin
-
-If you plan to create your own Gulp plugin, you will save time by reading the full documentation.

-* [Guidelines](guidelines.md) (a MUST read)
-* [Using buffers](using-buffers.md)
-* [Dealing with streams](dealing-with-streams.md)
-* [Testing](testing.md)
-* [README conventions](readme-conventions.md)
-
-## What it does
-
-### Streaming file objects
-
-A gulp plugin always returns a stream in [object mode](http://nodejs.org/api/stream.html#stream_object_mode) that does the following:
-
-1. Takes in [vinyl File objects](http://github.com/wearefractal/vinyl)
-2. Outputs [vinyl File objects](http://github.com/wearefractal/vinyl)
-
-These are known as [transform streams](http://nodejs.org/api/stream.html#stream_class_stream_transform_1) (also sometimes called through streams). Transform streams are streams that are readable and writable which manipulate objects as they're being passed through.
-
-### Modifying file content
-
-Vinyl files can have 3 possible forms for the contents attribute:
-
-- [Streams](dealing-with-streams.md)
-- [Buffers](using-buffers.md)
-- Empty (null) - Useful for things like rimraf, clean, where contents is not neeeded.
-
-## Useful resources

-* [BufferStream](https://github.com/nfroidure/BufferStream)

-
-
-## About streams
-
-If you're unfamiliar with streams, you will need to read up on them:
-
-* https://github.com/substack/stream-handbook (a MUST read)
-* http://nodejs.org/api/stream.html
-
-Other libraries that are not file manipulating through streams but are made for use with gulp are tagged with the [gulpfriendly](https://npmjs.org/browse/keyword/gulpfriendly) keyword on npm.

-
-[Writing a Plugin](README.md) > Writing stream based plugins
-
-## Dealing with streams
-
-Let's implement a plugin prepending some text to files. This plugin supports all possible forms of file.contents.
-
-```js
-var through = require('through2');
-var gutil = require('gulp-util');
-var PluginError = gutil.PluginError;
-
-// Consts
-const PLUGIN_NAME = 'gulp-prefixer';
-
-function prefixStream(prefixText) {
-  var stream = through();
-  stream.write(prefixText);
-  return stream;
-}
-
-// Plugin level function (dealing with files)
-function gulpPrefixer(prefixText) {
-
-  if (!prefixText) {
-    throw PluginError(PLUGIN_NAME, "Missing prefix text!");
-  }
-  prefixText = new Buffer(prefixText); // allocate ahead of time
-
-  // Creating a stream through which each file will pass
-  var stream = through.obj(function (file, enc, callback) {
-    if (file.isNull()) {
-      this.push(file); // Do nothing if no contents
-      return callback();
-    }
-
-    if (file.isBuffer()) {
-      this.emit('error', new PluginError(PLUGIN_NAME, 'Buffers not supported!'));
-      return callback();
-    }
-
-    if (file.isStream()) {
-      // define the streamer that will transform the content
-      var streamer = prefixStream(prefixText);
-      // catch errors from the streamer and emit a gulp plugin error
-      streamer.on('error', this.emit.bind(this, 'error'));
-      // start the transformation
-      file.contents = file.contents.pipe(streamer);
-      // make sure the file goes through the next gulp plugin
-      this.push(file);
-      // tell the stream engine that we are done with this file
-      return callback();
-    }
-  });
-
-  // returning the file stream
-  return stream;
-};
-
-// Exporting the plugin main function
-module.exports = gulpPrefixer;
-```
-
-The above plugin can be used like this:
-
-```js
-var gulp = require('gulp');
-var gulpPrefixer = require('gulp-prefixer');
-
-gulp.src('files/**/*.js')
-  .pipe(gulpPrefixer('prepended string'))
-  .pipe(gulp.dest('/modified-files/'));
-```

-# Guidelines
-
-> While these guidelines are totally optional, we **HIGHLY** recommend that everyone follows them. Nobody wants to use a bad plugin. These guidelines will actually help make your life easier by giving you assurance that your plugin fits well within gulp.
-
-[Writing a Plugin](README.md) > Guidelines
-
-1. Your plugin should not do something that can be done easily with an existing node module
-  - Wrapping every possible thing just for the sake of wrapping it will pollute the ecosystem with low quality plugins that don't make sense
-1. Your plugin should only do **one thing**, and do it well.
-  - Avoid config options that make your plugin do completely different tasks
-1. Your plugin shouldn't do things that other plugins are responsible for
-  - It should not concat, [gulp-concat](https://github.com/wearefractal/gulp-concat) does that
-  - It should not add headers, [gulp-header](https://github.com/godaddy/gulp-header) does that
-  - It should not add footers, [gulp-footer](https://github.com/godaddy/gulp-footer) does that
-  - If it's a common but optional use case, document that your plugin is often used with another plugin
-  - If it's an internal requirement, make use of existing plugins by piping your plugin's output to them
-1. Your plugin **must be tested**
-  - Testing a gulp plugin is easy, you don't even need gulp to test it
-  - Look at other plugins for examples
-1. Add `gulpplugin` as a keyword in your `package.json` so you show up on our search
-1. Do not throw errors inside a stream
-  - Instead, you should emit it as an **error** event.
-  - If you encounter an error **outside** the stream, such as invalid configuration, you may throw it.
-1. Prefix any errors with the name of your plugin
-  - For example: `gulp-replace: Cannot do regexp replace on a stream`
-  - Use gulp-util's [PluginError](https://github.com/gulpjs/gulp-util#new-pluginerrorpluginname-message-options) class to make this easy
-1. The type of `file.contents` should always be the same going out as it was when it came in
-  - If file.contents is null (non-read) just ignore the file and pass it along
-  - If file.contents is a Stream and you don't support that just emit an error
-  - If you choose to support file.contents as a Stream, use [BufferStream](https://github.com/nfroidure/BufferStream) to make this easy
-1. Do not pass the `file` object downstream until you are done with it
-1. Make use of the [gulp-util](https://github.com/gulpjs/gulp-util) library
-  - It provides templating, CLI colors, logging, changing file extensions
-  - Try looking for common things there first and add it if it doesn't exist
-1. Do NOT require `gulp` as a dependency or peerDependency
-  - There is no reason you should have to do this and it will cause problems if you do
-
-## Why are these guidelines so strict?
-
-gulp aims to be simple for users. By providing strict guidelines we are able to provide a consistent and high-quality ecosystem for everyone. While this does add a little more work and thought for plugin authors, it removes a lot of problems later down the road.
-
-### What happens if I don't follow them?
-
-npm is open for everyone, and you are free to make whatever you want but these guidelines were prescribed for a reason. There are acceptances tests coming soon that will be integrated into the plugin search. If you fail to adhere to the plugin guidelines it will be publicly visible/sortable via a scoring system. People will always prefer to use plugins that match "the gulp way".
-
-### What does a good plugin look like?
-
-```js
-// through2 is a thin wrapper around node transform streams
-var through = require('through2');
-var gutil = require('gulp-util');
-var PluginError = gutil.PluginError;
-
-// Consts
-const PLUGIN_NAME = 'gulp-prefixer';
-
-function prefixStream(prefixText) {
-  var stream = through();
-  stream.write(prefixText);
-  return stream;
-}
-
-// Plugin level function (dealing with files)
-function gulpPrefixer(prefixText) {
-
-  if (!prefixText) {
-    throw PluginError(PLUGIN_NAME, "Missing prefix text!");
-  }
-  prefixText = new Buffer(prefixText); // allocate ahead of time
-
-  // Creating a stream through which each file will pass
-  var stream = through.obj(function (file, enc, callback) {
-    if (file.isNull()) {
-      this.push(file); // Do nothing if no contents
-      return callback();
-    }
-
-    if (file.isBuffer()) {
-      file.contents = Buffer.concat([prefixText, file.contents]);
-      this.push(file);
-      return callback();
-    }
-
-    if (file.isStream()) {
-      file.contents = file.contents.pipe(prefixStream(prefixText));
-      this.push(file);
-      return callback();
-    }
-  });
-
-  // returning the file stream
-  return stream;
-};
-
-// Exporting the plugin main function
-module.exports = gulpPrefixer;

-# README conventions
-
-> Follow README conventions to increase your plugin readability and usability.
-
-[Writing a Gulp Plugin](README.md) > README conventions
-
-A plugin README should have the following parts at a minimum:
-
-1. **Heading**: Give a short introduction to your plugin
-  * Include the version of gulp your plugin was designed for
-  * Include any badges on the same line as the heading
-1. **Usage**: Include a simple usage example
-  * Show the plugin used on the context of a `gulpfile.js`
-  * Cover the most common or simplest use case 
-1. **API**: Document your plugin's API
-  * For individual parameters, include:
-    1. Parameter name
-    1. Type
-    1. Default value
-    1. Description
-    1. Optional example for complex options
-  * If a parameter accepts an Object, do the above for each property
-  * If your plugin accepts overloaded arguments, document each style individually
-
-
-# Example: Options object
-
-The following is an example of a plugin that takes a single options object (from [gulp-handlebars](https://github.com/lazd/gulp-handlebars)).
-
-
-***
-
-# gulp-handlebars [![NPM version][handlebars-npm-image]][handlebars-npm-url] [![Build status][handlebars-travis-image]][handlebars-travis-url]
-> Handlebars plugin for gulp 3
-
-## Usage
-
-First, install `gulp-handlebars` as a development dependency:
-
-```shell
-npm install --save-dev gulp-handlebars
-```
-
-Then, add it to your `gulpfile.js`:
-
-```js
-var handlebars = require('gulp-handlebars');
-
-gulp.task('templates', function(){
-  gulp.src(['client/templates/*.hbs'])
-    .pipe(handlebars({
-      namespace: 'MyApp.templates',
-      outputType: 'hybrid'
-     }))
-    .pipe(concat('templates.js'))
-    .pipe(gulp.dest('build/js/'));
-});
-```
-
-## API
-
-### handlebars(options)
-
-#### options.namespace
-Type: `String`  
-Default: `templates`
-
-The namespace in which the precompiled templates will be assigned. Use dot notation (e.g. `App.Templates`) for nested namespaces or false to declare templates in the global namespace.
-
-#### options.outputType
-Type: `String`  
-Default: `browser`
-
-The desired output type. One of the following:
-
-* `browser` - Produce plain JavaScript files for the browser
-* `hybrid` - Produce Node modules that can optionally be used on the frontend
-* `node` - Produce Node modules
-* `amd` - Produce AMD modules
-* `commonjs` - Produce CommonJS modules
-* `bare` - Return an unmolested function definition
-
-#### options.declareNamespace
-Type: `Boolean`  
-Default: `true`
-
-If true, non-destructively declare all parts of the namespace. This option is only necessary when `options.type` is `browser` or `hybrid`.
-
-For example, if the namespace is `MyApp.Templates` and a template is named `App.Header.hbs`, the following declaration will be present in the output file for that template:
-
-```js
-this["MyApp"] = this["MyApp"] || {};
-this["MyApp"]["templates"] = this["MyApp"]["templates"] || {};
-this["MyApp"]["templates"]["App"] = this["MyApp"]["templates"]["App"] || {};
-this["MyApp"]["templates"]["App"]["Header"] = function () {};
-```
-
-When processing multiple templates under a given namespace, this will result in duplicate declarations. That is, the non-destructive declaration of the namespace will be repeated for each template compiled.
-
-#### options.processName
-Type: `Function`  
-Default: Strip file extension
-
-This option accepts a function which takes one argument (the template filepath) and returns a string which will be used as the key for the precompiled template object. By default, the filename minus the extension is used.
-
-If this function returns a string containing periods (not including the file extension), they will be represented as a sub-namespace. See `options.declareNamespace` for an example of the effect.
-
-#### options.compilerOptions
-Type: `Object`
-
-Compiler options to pass to `Handlebars.precompile()`.

-
-
-# Example: Overloaded API
-
-The following is an example of a plugin that has an overloaded API (from [gulp-csslint](https://github.com/lazd/gulp-csslint)).
-
-
-***
-# gulp-csslint [![NPM version][csslint-npm-image]][csslint-npm-url] [![Build status][csslint-travis-image]][csslint-travis-url]
-> CSSLint plugin for gulp 3
-
-## Usage
-
-First, install `gulp-csslint` as a development dependency:
-
-```shell
-npm install --save-dev gulp-csslint
-```
-
-Then, add it to your `gulpfile.js`:
-
-```javascript
-var csslint = require('gulp-csslint');
-
-gulp.task('css', function() {
-  gulp.src('./client/css/*.css')
-    .pipe(csslint())
-    .pipe(csslint.reporter());
-});
-```
-
-## API
-
-### csslint(ruleConfiguration)
-
-#### ruleConfiguration
-Type: `Object`
-
-You can pass rule configuration as an object. See the [list of rules by ID on the CSSLint wiki](https://github.com/stubbornella/csslint/wiki/Rules-by-ID) for valid rule IDs.
-
-```javascript
-gulp.src('./client/css/*.css')
-  .pipe(csslint({
-    'shorthand': false
-  }))
-  .pipe(csslint.reporter());
-```
-
-### csslint(csslintrc)
-
-#### csslintrc
-Type: `String`
-
-You can also pass the path to your csslintrc file instead of a rule configuration object.
-
-```javascript
-gulp.src('./client/css/*.css')
-  .pipe(csslint('csslintrc.json'))
-  .pipe(csslint.reporter());
-```
-
-## Results
-
-Adds the following properties to the file object:
-
-```javascript
-file.csslint.success = true; // or false
-file.csslint.errorCount = 0; // number of errors returned by CSSLint
-file.csslint.results = []; // CSSLint errors
-file.csslint.opt = {}; // The options you passed to CSSLint
-```
-
-## Custom Reporters
-
-Custom reporter functions can be passed as `cssline.reporter(reporterFunc)`. The reporter function will be called for each linted file and passed the file object as described above.
-
-```javascript
-var csslint = require('gulp-csslint');
-var gutil = require('gulp-util');
-
-var customReporter = function(file) {
-  gutil.log(gutil.colors.cyan(file.csslint.errorCount)+' errors in '+gutil.colors.magenta(file.path));
-
-  file.csslint.results.forEach(function(result) {
-    gutil.log(result.error.message+' on line '+result.error.line);
-  });
-};
-
-gulp.task('lint', function() {
-  gulp.files('./lib/*.js')
-    .pipe(csslint())
-    .pipe(csslint.reporter(customReporter));
-});
-```

-# Testing
-
-> Testing your plugin is the only way to ensure quality. It brings confidence to your users and makes your life easier.
-
-[Writing a Plugin](README.md) > Testing
-
-## Tooling
-
-Most plugins use [mocha](https://github.com/visionmedia/mocha) and [event-stream](https://github.com/dominictarr/event-stream) to help them test. The following examples will use these tools.
-
-## Testing plugins for streaming mode
-
-```js
-var assert = require('assert');
-var es = require('event-stream');
-var gutil = require('gulp-util');
-var prefixer = require('../index');
-
-describe('gulp-prefixer', function () {
-  describe('in streaming mode', function () {
-
-    it('should prepend text', function (done) {
-
-      // create the fake file
-      var fakeFile = new gutil.File({
-        contents: es.readArray(['stream', 'with', 'those', 'contents'])
-      });
-
-      // Create a prefixer plugin stream
-      var myPrefixer = prefixer('prependthis');
-
-      // write the fake file to it
-      myPrefixer.write(fakeFile);
-
-      // wait for the file to come back out
-      myPrefixer.once('data', function (file) {
-        // make sure it came out the same way it went in
-        assert(file.isStream());
-
-        // buffer the contents to make sure it got prepended to
-        file.contents.pipe(es.wait(function (err, data) {
-          // check the contents
-          assert.equal(data, 'prependthistostreamwiththosecontents');
-          done();
-        }));
-      });
-
-    });
-
-  });
-});

-# Using buffers
-
-> Here is some information on creating gulp plugin that manipulates buffers.
-
-[Writing a Plugin](README.md) > Using buffers
-
-## Using buffers
-If your plugin is relying on a buffer based library, you will probably choose to base your plugin around file.contents as a buffer. Let's implement a plugin prepending some text to files:
-
-```js
-var through = require('through2');
-var gutil = require('gulp-util');
-var PluginError = gutil.PluginError;
-
-// Consts
-const PLUGIN_NAME = 'gulp-prefixer';
-
-// Plugin level function (dealing with files)
-function gulpPrefixer(prefixText) {
-
-  if (!prefixText) {
-    throw new PluginError(PLUGIN_NAME, "Missing prefix text!");
-  }
-  prefixText = new Buffer(prefixText); // allocate ahead of time
-
-  // Creating a stream through which each file will pass
-  var stream = through.obj(function (file, enc, callback) {
-    if (file.isNull()) {
-      this.push(file); // Do nothing if no contents
-      return callback();
-    }
-
-    if (file.isBuffer()) {
-      file.contents = Buffer.concat([prefixText, file.contents]);
-      this.push(file);
-      return callback();
-    }
-
-    if (file.isStream()) {
-      this.emit('error', new PluginError(PLUGIN_NAME, 'Streams are not supported!'));
-      return callback();
-    }
-  });
-
-  // returning the file stream
-  return stream;
-};
-
-// Exporting the plugin main function
-module.exports = gulpPrefixer;
-```
-The above plugin can be used like this:
-
-```js
-var gulp = require('gulp');
-var gulpPrefixer = require('gulp-prefixer');
-
-gulp.src('files/**/*.js')
-  .pipe(gulpPrefixer('prepended string'))
-  .pipe(gulp.dest('/modified-files/'));
-```
-
-## Handling streams
-
-Unfortunately, the above plugin will error when using gulp.src in non-buffered (streaming) mode. You should support streams too if possible. See [Dealing with streams](dealing-with-streams.md) for more information.

Although there are other ones, they either do too much or not enough.\n\n**Chalk is a clean and focused alternative.**\n\n![screenshot](screenshot.png)\n\n\n## Why\n\n- **Doesn't extend String.prototype**\n- Expressive API\n- Clean and focused\n- Auto-detects color support\n- Actively maintained\n- [Used by 150+ modules](https://npmjs.org/browse/depended/chalk)\n\n\n## Install\n\nInstall with [npm](https://npmjs.org/package/chalk): `npm install --save chalk`\n\n\n## Example\n\nChalk comes with an easy to use composable API where you just chain and nest the styles you want.\n\n```js\nvar chalk = require('chalk');\n\n// style a string\nconsole.log(  chalk.blue('Hello world!')  );\n\n// combine styled and normal strings\nconsole.log(  chalk.blue('Hello'), 'World' + chalk.red('!')  );\n\n// compose multiple styles using the chainable API\nconsole.log(  chalk.blue.bgRed.bold('Hello world!')  );\n\n// nest styles\nconsole.log(  chalk.red('Hello', chalk.underline.bgBlue('world') + '!')  );\n\n// pass in multiple arguments\nconsole.log(  chalk.blue('Hello', 'World!', 'Foo', 'bar', 'biz', 'baz')  );\n```\n\nYou can easily define your own themes.\n\n```js\nvar chalk = require('chalk');\nvar error = chalk.bold.red;\nconsole.log(error('Error!'));\n```\n\n\n## API\n\n### chalk.`<style>[.<style>...](string, [string...])`\n\nExample: `chalk.red.bold.underline('Hello', 'world');`\n\nChain [styles](#styles) and call the last one as a method with a string argument. Order doesn't matter.\n\nMultiple arguments will be separated by space.\n\n### chalk.enabled\n\nColor support is automatically detected, but you can override it.\n\n### chalk.supportsColor\n\nDetect whether the terminal [supports color](https://github.com/sindresorhus/has-color).\n\nCan be overridden by the user with the flags `--color` and `--no-color`.\n\nUsed internally and handled for you, but exposed for convenience.\n\n### chalk.styles\n\nExposes the styles as [ANSI escape codes](https://github.com/sindresorhus/ansi-styles).\n\nGenerally not useful, but you might need just the `.open` or `.close` escape code if you're mixing externally styled strings with yours.\n\n```js\nvar chalk = require('chalk');\n\nconsole.log(chalk.styles.red);\n//=> {open: '\\x1b[31m', close: '\\x1b[39m'}\n\nconsole.log(chalk.styles.red.open + 'Hello' + chalk.styles.red.close);\n```\n\n### chalk.stripColor(string)\n\n[Strip color](https://github.com/sindresorhus/strip-ansi) from a string.\n\nCan be useful in combination with `.supportsColor` to strip color on externally styled text when it's not supported.\n\nExample:\n\n```js\nvar chalk = require('chalk');\nvar styledString = fromExternal();\n\nif (!chalk.supportsColor) {\n\tchalk.stripColor(styledString);\n}\n```\n\n\n## Styles\n\n### General\n\n- reset\n- bold\n- italic\n- underline\n- inverse\n- strikethrough\n\n### Text colors\n\n- black\n- red\n- green\n- yellow\n- blue\n- magenta\n- cyan\n- white\n- gray\n\n### Background colors\n\n- bgBlack\n- bgRed\n- bgGreen\n- bgYellow\n- bgBlue\n- bgMagenta\n- bgCyan\n- bgWhite\n\n\n## License\n\nMIT © [Sindre Sorhus](http://sindresorhus.com)\n\n\n-\n\n[![Bitdeli Badge](https://d2weczhvl823v0.cloudfront.net/sindresorhus/chalk/trend.png)](https://bitdeli.com/free \"Bitdeli Badge\")\n",

+Chalk comes with an easy to use composable API where you just chain and nest the styles you want.
+
+```js
+var chalk = require('chalk');
+
+// style a string
+console.log(  chalk.blue('Hello world!')  );
+
+// combine styled and normal strings
+console.log(  chalk.blue('Hello'), 'World' + chalk.red('!')  );
+
+// compose multiple styles using the chainable API
+console.log(  chalk.blue.bgRed.bold('Hello world!')  );
+
+// nest styles
+console.log(  chalk.red('Hello', chalk.underline.bgBlue('world') + '!')  );
+
+// pass in multiple arguments
+console.log(  chalk.blue('Hello', 'World!', 'Foo', 'bar', 'biz', 'baz')  );
+```
+
+You can easily define your own themes.
+
+```js
+var chalk = require('chalk');
+var error = chalk.bold.red;
+console.log(error('Error!'));
+```
+
+
+## API
+
+### chalk.`<style>[.<style>...](string, [string...])`
+
+Example: `chalk.red.bold.underline('Hello', 'world');`
+
+Chain [styles](#styles) and call the last one as a method with a string argument. Order doesn't matter.
+
+Multiple arguments will be separated by space.
+
+### chalk.enabled
+
+Color support is automatically detected, but you can override it.
+
+### chalk.supportsColor
+
+Detect whether the terminal [supports color](https://github.com/sindresorhus/has-color).
+
+Can be overridden by the user with the flags `--color` and `--no-color`.
+
+Used internally and handled for you, but exposed for convenience.
+
+### chalk.styles
+
+Exposes the styles as [ANSI escape codes](https://github.com/sindresorhus/ansi-styles).
+
+Generally not useful, but you might need just the `.open` or `.close` escape code if you're mixing externally styled strings with yours.
+
+```js
+var chalk = require('chalk');
+
+console.log(chalk.styles.red);
+//=> {open: '\x1b[31m', close: '\x1b[39m'}
+
+console.log(chalk.styles.red.open + 'Hello' + chalk.styles.red.close);
+```
+
+### chalk.stripColor(string)
+
+[Strip color](https://github.com/sindresorhus/strip-ansi) from a string.
+
+Can be useful in combination with `.supportsColor` to strip color on externally styled text when it's not supported.
+
+Example:
+
+```js
+var chalk = require('chalk');
+var styledString = fromExternal();
+
+if (!chalk.supportsColor) {
+	chalk.stripColor(styledString);
+}
+```

-# graceful-fs
-
-graceful-fs functions as a drop-in replacement for the fs module,
-making various improvements.
-
-The improvements are meant to normalize behavior across different
-platforms and environments, and to make filesystem access more
-resilient to errors.
-
-## Improvements over fs module
-
-graceful-fs:
-
-* keeps track of how many file descriptors are open, and by default
-  limits this to 1024. Any further requests to open a file are put in a
-  queue until new slots become available. If 1024 turns out to be too
-  much, it decreases the limit further.
-* fixes `lchmod` for Node versions prior to 0.6.2.
-* implements `fs.lutimes` if possible. Otherwise it becomes a noop.
-* ignores `EINVAL` and `EPERM` errors in `chown`, `fchown` or
-  `lchown` if the user isn't root.
-* makes `lchmod` and `lchown` become noops, if not available.
-* retries reading a file if `read` results in EAGAIN error.
-
-On Windows, it retries renaming a file for up to one second if `EACCESS`
-or `EPERM` error occurs, likely because antivirus software has locked
-the directory.
-
-## Configuration
-
-The maximum number of open file descriptors that graceful-fs manages may
-be adjusted by setting `fs.MAX_OPEN` to a different number. The default
-is 1024.

Otherwise it becomes a noop.\n* ignores `EINVAL` and `EPERM` errors in `chown`, `fchown` or\n  `lchown` if the user isn't root.\n* makes `lchmod` and `lchown` become noops, if not available.\n* retries reading a file if `read` results in EAGAIN error.\n\nOn Windows, it retries renaming a file for up to one second if `EACCESS`\nor `EPERM` error occurs, likely because antivirus software has locked\nthe directory.\n\n## Configuration\n\nThe maximum number of open file descriptors that graceful-fs manages may\nbe adjusted by setting `fs.MAX_OPEN` to a different number. The default\nis 1024.\n",

It uses the `minimatch`\nlibrary to do its matching.\n\n## Attention: node-glob users!\n\nThe API has changed dramatically between 2.x and 3.x. This library is\nnow 100% JavaScript, and the integer flags have been replaced with an\noptions object.\n\nAlso, there's an event emitter class, proper tests, and all the other\nthings you've come to expect from node modules.\n\nAnd best of all, no compilation!\n\n## Usage\n\n```javascript\nvar glob = require(\"glob\")\n\n// options is optional\nglob(\"**/*.js\", options, function (er, files) {\n  // files is an array of filenames.\n  // If the `nonull` option is set, and nothing\n  // was found, then files is [\"**/*.js\"]\n  // er is an error object or null.\n})\n```\n\n## Features\n\nPlease see the [minimatch\ndocumentation](https://github.com/isaacs/minimatch) for more details.\n\nSupports these glob features:\n\n* Brace Expansion\n* Extended glob matching\n* \"Globstar\" `**` matching\n\nSee:\n\n* `man sh`\n* `man bash`\n* `man 3 fnmatch`\n* `man 5 gitignore`\n* [minimatch documentation](https://github.com/isaacs/minimatch)\n\n## glob(pattern, [options], cb)\n\n* `pattern` {String} Pattern to be matched\n* `options` {Object}\n* `cb` {Function}\n  * `err` {Error | null}\n  * `matches` {Array<String>} filenames found matching the pattern\n\nPerform an asynchronous glob search.\n\n## glob.sync(pattern, [options]\n\n* `pattern` {String} Pattern to be matched\n* `options` {Object}\n* return: {Array<String>} filenames found matching the pattern\n\nPerform a synchronous glob search.\n\n## Class: glob.Glob\n\nCreate a Glob object by instanting the `glob.Glob` class.\n\n```javascript\nvar Glob = require(\"glob\").Glob\nvar mg = new Glob(pattern, options, cb)\n```\n\nIt's an EventEmitter, and starts walking the filesystem to find matches\nimmediately.\n\n### new glob.Glob(pattern, [options], [cb])\n\n* `pattern` {String} pattern to search for\n* `options` {Object}\n* `cb` {Function} Called when an error occurs, or matches are found\n  * `err` {Error | null}\n  * `matches` {Array<String>} filenames found matching the pattern\n\nNote that if the `sync` flag is set in the options, then matches will\nbe immediately available on the `g.found` member.\n\n### Properties\n\n* `minimatch` The minimatch object that the glob uses.\n* `options` The options object passed in.\n* `error` The error encountered.  When an error is encountered, the\n  glob object is in an undefined state, and should be discarded.\n* `aborted` Boolean which is set to true when calling `abort()`.  There\n  is no way at this time to continue a glob search after aborting, but\n  you can re-use the statCache to avoid having to duplicate syscalls.\n\n### Events\n\n* `end` When the matching is finished, this is emitted with all the\n  matches found.  If the `nonull` option is set, and no match was found,\n  then the `matches` list contains the original pattern.  The matches\n  are sorted, unless the `nosort` flag is set.\n* `match` Every time a match is found, this is emitted with the matched.\n* `error` Emitted when an unexpected error is encountered, or whenever\n  any fs error occurs if `options.strict` is set.\n* `abort` When `abort()` is called, this event is raised.\n\n### Methods\n\n* `abort` Stop the search.\n\n### Options\n\nAll the options that can be passed to Minimatch can also be passed to\nGlob to change pattern matching behavior.  Also, some have been added,\nor have glob-specific ramifications.\n\nAll options are false by default, unless otherwise noted.\n\nAll options are added to the glob object, as well.\n\n* `cwd` The current working directory in which to search.  Defaults\n  to `process.cwd()`.\n* `root` The place where patterns starting with `/` will be mounted\n  onto.  Defaults to `path.resolve(options.cwd, \"/\")` (`/` on Unix\n  systems, and `C:\\` or some such on Windows.)\n* `nomount` By default, a pattern starting with a forward-slash will be\n  \"mounted\" onto the root setting, so that a valid filesystem path is\n  returned.  Set this flag to disable that behavior.\n* `mark` Add a `/` character to directory matches.  Note that this\n  requires additional stat calls.\n* `nosort` Don't sort the results.\n* `stat` Set to true to stat *all* results.  This reduces performance\n  somewhat, and is completely unnecessary, unless `readdir` is presumed\n  to be an untrustworthy indicator of file existence.  It will cause\n  ELOOP to be triggered one level sooner in the case of cyclical\n  symbolic links.\n* `silent` When an unusual error is encountered\n  when attempting to read a directory, a warning will be printed to\n  stderr.  Set the `silent` option to true to suppress these warnings.\n* `strict` When an unusual error is encountered\n  when attempting to read a directory, the process will just continue on\n  in search of other matches.  Set the `strict` option to raise an error\n  in these cases.\n* `statCache` A cache of results of filesystem information, to prevent\n  unnecessary stat calls.  While it should not normally be necessary to\n  set this, you may pass the statCache from one glob() call to the\n  options object of another, if you know that the filesystem will not\n  change between calls.  (See \"Race Conditions\" below.)\n* `sync` Perform a synchronous glob search.\n* `nounique` In some cases, brace-expanded patterns can result in the\n  same file showing up multiple times in the result set.  By default,\n  this implementation prevents duplicates in the result set.\n  Set this flag to disable that behavior.\n* `nonull` Set to never return an empty set, instead returning a set\n  containing the pattern itself.  This is the default in glob(3).\n* `nocase` Perform a case-insensitive match.  Note that case-insensitive\n  filesystems will sometimes result in glob returning results that are\n  case-insensitively matched anyway, since readdir and stat will not\n  raise an error.\n* `debug` Set to enable debug logging in minimatch and glob.\n* `globDebug` Set to enable debug logging in glob, but not minimatch.\n\n## Comparisons to other fnmatch/glob implementations\n\nWhile strict compliance with the existing standards is a worthwhile\ngoal, some discrepancies exist between node-glob and other\nimplementations, and are intentional.\n\nIf the pattern starts with a `!` character, then it is negated.  Set the\n`nonegate` flag to suppress this behavior, and treat leading `!`\ncharacters normally.  This is perhaps relevant if you wish to start the\npattern with a negative extglob pattern like `!(a|B)`.  Multiple `!`\ncharacters at the start of a pattern will negate the pattern multiple\ntimes.\n\nIf a pattern starts with `#`, then it is treated as a comment, and\nwill not match anything.  Use `\\#` to match a literal `#` at the\nstart of a line, or set the `nocomment` flag to suppress this behavior.\n\nThe double-star character `**` is supported by default, unless the\n`noglobstar` flag is set.  This is supported in the manner of bsdglob\nand bash 4.1, where `**` only has special significance if it is the only\nthing in a path part.  That is, `a/**/b` will match `a/x/y/b`, but\n`a/**b` will not.  **Note that this is different from the way that `**` is\nhandled by ruby's `Dir` class.**\n\nIf an escaped pattern has no matches, and the `nonull` flag is set,\nthen glob returns the pattern as-provided, rather than\ninterpreting the character escapes.  For example,\n`glob.match([], \"\\\\*a\\\\?\")` will return `\"\\\\*a\\\\?\"` rather than\n`\"*a?\"`.  This is akin to setting the `nullglob` option in bash, except\nthat it does not resolve escaped pattern characters.\n\nIf brace expansion is not disabled, then it is performed before any\nother interpretation of the glob pattern.  Thus, a pattern like\n`+(a|{b),c)}`, which would not be valid in bash or zsh, is expanded\n**first** into the set of `+(a|b)` and `+(a|c)`, and those patterns are\nchecked for validity.  Since those two are valid, matching proceeds.\n\n## Windows\n\n**Please only use forward-slashes in glob expressions.**\n\nThough windows uses either `/` or `\\` as its path separator, only `/`\ncharacters are used by this glob implementation.  You must use\nforward-slashes **only** in glob expressions.  Back-slashes will always\nbe interpreted as escape characters, not path separators.\n\nResults from absolute patterns such as `/foo/*` are mounted onto the\nroot setting using `path.join`.  On windows, this will by default result\nin `/foo/*` matching `C:\\foo\\bar.txt`.\n\n## Race Conditions\n\nGlob searching, by its very nature, is susceptible to race conditions,\nsince it relies on directory walking and such.\n\nAs a result, it is possible that a file that exists when glob looks for\nit may have been deleted or modified by the time it returns the result.\n\nAs part of its internal implementation, this program caches all stat\nand readdir calls that it makes, in order to cut down on system\noverhead.  However, this also makes it even more susceptible to races,\nespecially if the statCache object is reused between glob calls.\n\nUsers are thus advised not to use a glob result as a\nguarantee of filesystem state in the face of rapid changes.\nFor the vast majority of operations, this is never a problem.\n",

[CascadiaJS: Lo-Dash for a better utility belt](http://www.youtube.com/watch?v=dpPy4f_SeEk)\n\n## Features\n\n * AMD loader support ([RequireJS](http://requirejs.org/), [curl.js](https://github.com/cujojs/curl), etc.)\n * [_(…)](http://lodash.com/docs#_) supports intuitive chaining\n * [_.at](http://lodash.com/docs#at) for cherry-picking collection values\n * [_.bindKey](http://lodash.com/docs#bindKey) for binding [*“lazy”* defined](http://michaux.ca/articles/lazy-function-definition-pattern) methods\n * [_.cloneDeep](http://lodash.com/docs#cloneDeep) for deep cloning arrays and objects\n * [_.contains](http://lodash.com/docs#contains) accepts a `fromIndex` argument\n * [_.forEach](http://lodash.com/docs#forEach) is chainable and supports exiting iteration early\n * [_.forIn](http://lodash.com/docs#forIn) for iterating over an object’s own and inherited properties\n * [_.forOwn](http://lodash.com/docs#forOwn) for iterating over an object’s own properties\n * [_.isPlainObject](http://lodash.com/docs#isPlainObject) checks if values are created by the `Object` constructor\n * [_.merge](http://lodash.com/docs#merge) for a deep [_.extend](http://lodash.com/docs#extend)\n * [_.partial](http://lodash.com/docs#partial) and [_.partialRight](http://lodash.com/docs#partialRight) for partial application without `this` binding\n * [_.template](http://lodash.com/docs#template) supports [*“imports”* options](http://lodash.com/docs#templateSettings_imports), [ES6 template delimiters](http://people.mozilla.org/~jorendorff/es6-draft.html#sec-7.8.6), and [sourceURLs](http://www.html5rocks.com/en/tutorials/developertools/sourcemaps/#toc-sourceurl)\n * [_.where](http://lodash.com/docs#where) supports deep object comparisons\n * [_.clone](http://lodash.com/docs#clone), [_.omit](http://lodash.com/docs#omit), [_.pick](http://lodash.com/docs#pick),\n   [and more…](http://lodash.com/docs \"_.assign, _.cloneDeep, _.first, _.initial, _.isEqual, _.last, _.merge, _.rest\") accept `callback` and `thisArg` arguments\n * [_.contains](http://lodash.com/docs#contains), [_.size](http://lodash.com/docs#size), [_.toArray](http://lodash.com/docs#toArray),\n   [and more…](http://lodash.com/docs \"_.at, _.countBy, _.every, _.filter, _.find, _.forEach, _.groupBy, _.invoke, _.map, _.max, _.min, _.pluck, _.reduce, _.reduceRight, _.reject, _.shuffle, _.some, _.sortBy, _.where\") accept strings\n * [_.filter](http://lodash.com/docs#filter), [_.find](http://lodash.com/docs#find), [_.map](http://lodash.com/docs#map),\n   [and more…](http://lodash.com/docs \"_.countBy, _.every, _.first, _.groupBy, _.initial, _.last, _.max, _.min, _.reject, _.rest, _.some, _.sortBy, _.sortedIndex, _.uniq\") support *“_.pluck”* and *“_.where”* `callback` shorthands\n\n## Support\n\nLo-Dash has been tested in at least Chrome 5~24, Firefox 1~18, IE 6-10, Opera 9.25-12, Safari 3-6, Node.js 0.4.8-0.8.20, Narwhal 0.3.2, PhantomJS 1.8.1, RingoJS 0.9, and Rhino 1.7RC5.\n\n## Installation and usage\n\nIn browsers:\n\n```html\n<script src=\"lodash.js\"></script>\n```\n\nUsing [`npm`](http://npmjs.org/):\n\n```bash\nnpm install lodash\n\nnpm install -g lodash\nnpm link lodash\n```\n\nTo avoid potential issues, update `npm` before installing Lo-Dash:\n\n```bash\nnpm install npm -g\n```\n\nIn [Node.js](http://nodejs.org/) and [RingoJS v0.8.0+](http://ringojs.org/):\n\n```js\nvar _ = require('lodash');\n\n// or as a drop-in replacement for Underscore\nvar _ = require('lodash/lodash.underscore');\n```\n\n**Note:** If Lo-Dash is installed globally, run [`npm link lodash`](http://blog.nodejs.org/2011/03/23/npm-1-0-global-vs-local-installation/) in your project’s root directory before requiring it.\n\nIn [RingoJS v0.7.0-](http://ringojs.org/):\n\n```js\nvar _ = require('lodash')._;\n```\n\nIn [Rhino](http://www.mozilla.org/rhino/):\n\n```js\nload('lodash.js');\n```\n\nIn an AMD loader like [RequireJS](http://requirejs.org/):\n\n```js\nrequire({\n  'paths': {\n    'underscore': 'path/to/lodash'\n  }\n},\n['underscore'], function(_) {\n  console.log(_.VERSION);\n});\n```\n\n## Release Notes\n\n### <sup>v1.0.1</sup>\n\n * Add support for specifying source map URLs in `-p`/`--source-map` build options\n * Ensured the second argument passed to `_.assign` is not treated as a `callback`\n * Ensured `-p`/`--source-map` build options correctly set the `sourceMappingURL`\n * Made `-p`/`--source-map` build options set source map *“sources”* keys based on the builds performed\n * Made `_.defer` use `setImmediate`, in Node.js, when available\n * Made `_.where` search arrays for values regardless of their index position\n * Removed dead code from `_.template`\n\nThe full changelog is available [here](https://github.com/lodash/lodash/wiki/Changelog).\n\n## BestieJS\n\nLo-Dash is part of the [BestieJS](https://github.com/bestiejs) *“Best in Class”* module collection. This means we promote solid browser/environment support, ES5 precedents, unit testing, and plenty of documentation.\n\n## Author\n\n| [![twitter/jdalton](http://gravatar.com/avatar/299a3d891ff1920b69c364d061007043?s=70)](http://twitter.com/jdalton \"Follow @jdalton on Twitter\") |\n|---|\n| [John-David Dalton](http://allyoucanleet.com/) |\n\n## Contributors\n\n| [![twitter/blainebublitz](http://gravatar.com/avatar/ac1c67fd906c9fecd823ce302283b4c1?s=70)](http://twitter.com/blainebublitz \"Follow @BlaineBublitz on Twitter\") | [![twitter/kitcambridge](http://gravatar.com/avatar/6662a1d02f351b5ef2f8b4d815804661?s=70)](https://twitter.com/kitcambridge \"Follow @kitcambridge on Twitter\") | [![twitter/mathias](http://gravatar.com/avatar/24e08a9ea84deb17ae121074d0f17125?s=70)](http://twitter.com/mathias \"Follow @mathias on Twitter\") |\n|---|---|---|\n| [Blaine Bublitz](http://iceddev.com/) | [Kit Cambridge](http://kitcambridge.github.io/) | [Mathias Bynens](http://mathiasbynens.be/) |\n",

Or just filenames.\n\n### minimatchOptions\nType: `Object`  \nDefault: `{}`\n\nOptions to be passed to [minimatch](https://github.com/isaacs/minimatch).\n\nNote that if you want to start in a different directory than the current working directory, specify a `cwd` property here.\n\n## Contributing\nIn lieu of a formal styleguide, take care to maintain the existing coding style. Add unit tests for any new or changed functionality. Lint and test your code using [Grunt](http://gruntjs.com/).\n\n## Release History\n2013-03-08 - v0.1.2 - Updated dependencies. Fixed a Node 0.9.x bug. Updated unit tests to work cross-platform.  \n2012-11-15 - v0.1.1 - Now works without an options object.  \n2012-11-01 - v0.1.0 - Initial release.\n",

+# liftoff [![Build Status](https://secure.travis-ci.org/tkellen/node-liftoff.png)](http://travis-ci.org/tkellen/node-liftoff)
+> Launch your command line tool with ease.
+
+[![NPM](https://nodei.co/npm/liftoff.png)](https://nodei.co/npm/liftoff/)
+
+## What is it?
+[See this blog post, or read on.](http://weblog.bocoup.com/building-command-line-tools-in-node-with-liftoff/)
+
+Say you're writing a CLI tool.  Let's call it [hacker](http://github.com/tkellen/node-hacker).  You want to configure it using a `Hackerfile`.  This is node, so you install `hacker` locally for each project you use it in.  But, in order to get the `hacker` command in your PATH, you also install it globally.
+
+Now, when you run the `hacker` command, you want it to use the `Hackerfile` in your current directory, and the local installation of `hacker` next to it.  It'd be nice if it traversed up your folders until it found a `Hackerfile`&mdash;for those times when you're not in the root directory of your project.  Heck, you might even want to launch it from a folder outside of your project by manually specifying a working directory.  Liftoff manages this for you.
+
+So, everything is working great.  Now you can find your local `hacker` and `Hackerfile` with ease.  Unfortunately, it turns out you've authored your `Hackerfile` in coffee-script, or some other JS variant.  In order to support *that*, you have to load the compiler for it, and then register the extension for it with node.  Good news, Liftoff can do that too.
+
+## API
+
+### constructor(opts)
+
+Create an instance of Liftoff to invoke your application.
+
+An example utilizing all options:
+```js
+var Hacker = new Liftoff({
+  name: 'hacker',
+  moduleName: 'hacker',
+  configName: 'hackerfile',
+  addExtensions: ['.anything'],
+  processTitle: 'hacker',
+  cwdFlag: 'cwd',
+  configPathFlag: 'hackerfile',
+  preloadFlag: 'require',
+  completionFlag: 'completion',
+  completions: function (type) {
+    console.log('Completions not implemented.');
+  }
+});
+```
+
+#### opts.name
+
+Sugar for setting `processTitle`, `moduleName`, `configName` & `configPathFlag` automatically.
+
+Type: `String`
+Default: `null`
+
+These are equivalent:
+```js
+new Liftoff({
+  processTitle: 'hacker',
+  moduleName: 'hacker',
+  configName: 'hackerfile',
+  configPathFlag: 'hackerfile'
+});
+```
+```js
+new Liftoff({name:'hacker'});
+```
+
+#### opts.moduleName
+
+Sets which module your application expects to find locally when being run.
+
+Type: `String`
+Default: `null`
+
+#### opts.configName
+
+Sets the name of the configuration file Liftoff will attempt to find.  Case-insensitive.
+
+Type: `String`
+Default: `null`
+
+#### opts.addExtensions
+
+Explicitly add custom extensions to include when searching for a configuration file.  Node supports `.js`, `.json` & `.node` natively, so there is no need to add these.
+
+An example usage for this setting would be to add an `rc` extension.  e.g. with a configName of `.myapp`, you want Liftoff to look for `.myapp{rc,.js,.json,.node}`
+
+Type: `Array`
+Default: `[]`
+
+#### opts.processTitle
+
+Sets what the [process title](http://nodejs.org/api/process.html#process_process_title) will be.
+
+Type: `String`
+Default: `null`
+
+#### opts.cwdFlag
+
+Sets what flag to use for altering the current working directory.  For example, `myapp --cwd ../` would invoke your application as though you'd called it from the parent of your current directory.
+
+Type: `String`
+Default: `cwd`
+
+#### opts.configPathFlag
+
+Sets what flag to use for defining the path to your configfile.  For example, `myapp --myappfile ../Myappfile.js` would explicitly specify the location of your config file.
+
+Type: `String`
+Default: `same as configName`
+
+#### opts.modulePathFlag
+
+Sets what flag to use for defining the path to your locally installed module.  For example, `myapp --myappdir ~/` would specify the location of your config file.  This option overrides `cwdFlag`.
+
+Type: `String`
+Default: `same as configName`
+
+#### opts.preloadFlag
+
+Sets what flag to use for pre-loading modules.  For example, `myapp --require coffee-script` would require a local version of coffee-script (if available) before attempting to find your configuration file.  If your required module registers a new
+[require.extension](http://nodejs.org/api/globals.html#globals_require_extensions), it will be included as an option when looking for a file matching `configName`.
+
+Type: `String`
+Default: `"require"`
+
+#### opts.completions(type)
+
+A method to handle bash/zsh/whatever completions.
+
+Type: `Function`
+Default: `null`
+
+### events
+
+#### require(name, module)
+
+Emitted when a module is pre-loaded.
+
+```js
+var Hacker = new Liftoff({name:'hacker'});
+Hacker.on('require', function (name, module) {
+  console.log('Requiring external module: '+name+'...');
+  // automatically register coffee-script extensions
+  if (name === 'coffee-script') {
+    module.register();
+  }
+});
+```
+
+#### requireFail(name, err)
+
+Emitted when a requested module cannot be preloaded.
+
+```js
+var Hacker = new Liftoff({name:'hacker'});
+Hacker.on('requireFail', function (name, err) {
+  console.log('Unable to load:', name, err);
+});
+```
+
+### launch(fn, argv)
+
+#### fn(env)
+
+A function to start your application.  When invoked, `this` will be your instance of Liftoff.  The `env` param will contain the following keys:
+
+- `argv`: cli arguments, as parsed by [minimist](https://npmjs.org/package/minimist), or as passed in manually.
+- `cwd`: the current working directory
+- `preload`: an array of modules that liftoff tried to pre-load
+- `validExtensions`: an array of supported extensions for your config file
+- `configNameRegex`: the regular expression used to find your config file
+- `configPath`: the full path to your configuration file (if found)
+- `configBase`: the base directory of your configuration file (if found)
+- `modulePath`: the full path to the local module your project relies on (if found)
+- `modulePackage`: the contents of the local module's package.json (if found)
+
+#### argv
+Manually specify command line arguments.  Useful for invoking the CLI programmatically.
+
+Type: `Object`
+Default: `null`
+
+## Examples
+Check out [the hacker project](https://github.com/tkellen/node-hacker/blob/master/bin/hacker.js) to see a working example of this tool.
+
+To try the example, do the following:
+
+1. Install the sample project `hacker` with `npm install -g hacker`.
+2. Make a `Hackerfile.js` with some arbitrary javascript it.
+3. Install hacker next to it with `npm install hacker`.
+3. Run `hacker` while in the same parent folder.
+
+For extra credit, try writing your `Hackerfile` in coffeescript.  Then, run `hacker --require coffee-script`.  Make sure you install coffee-script locally, though.

+# extend() for Node.js <sup>[![Version Badge][8]][3]</sup>
+
+`node-extend` is a port of the classic extend() method from jQuery. It behaves as you expect. It is simple, tried and true.
+
+## Installation
+
+This package is available on [npm][3] as: `extend`
+
+``` sh
+npm install extend
+```
+
+## Usage
+
+**Syntax:** extend **(** [`deep`], `target`, `object1`, [`objectN`] **)** 
+
+*Extend one object with one or more others, returning the modified object.*
+
+Keep in mind that the target object will be modified, and will be returned from extend().
+
+If a boolean true is specified as the first argument, extend performs a deep copy, recursively copying any objects it finds. Otherwise, the copy will share structure with the original object(s).
+Undefined properties are not copied. However, properties inherited from the object's prototype will be copied over.
+
+### Arguments
+
+* `deep` *Boolean* (optional)  
+If set, the merge becomes recursive (i.e. deep copy).
+* `target`	*Object*  
+The object to extend.
+* `object1`	*Object*  
+The object that will be merged into the first.
+* `objectN` *Object* (Optional)  
+More objects to merge into the first.
+
+## License
+
+`node-extend` is licensed under the [MIT License][4].
+
+## Acknowledgements
+
+All credit to the jQuery authors for perfecting this amazing utility.
+
+Ported to Node.js by [Stefan Thomas][5] with contributions by [Jonathan Buchanan][6] and [Jordan Harband][7].

It behaves as you expect. It is simple, tried and true.\n\n## Installation\n\nThis package is available on [npm][3] as: `extend`\n\n``` sh\nnpm install extend\n```\n\n## Usage\n\n**Syntax:** extend **(** [`deep`], `target`, `object1`, [`objectN`] **)** \n\n*Extend one object with one or more others, returning the modified object.*\n\nKeep in mind that the target object will be modified, and will be returned from extend().\n\nIf a boolean true is specified as the first argument, extend performs a deep copy, recursively copying any objects it finds. Otherwise, the copy will share structure with the original object(s).\nUndefined properties are not copied. However, properties inherited from the object's prototype will be copied over.\n\n### Arguments\n\n* `deep` *Boolean* (optional)  \nIf set, the merge becomes recursive (i.e. deep copy).\n* `target`\t*Object*  \nThe object to extend.\n* `object1`\t*Object*  \nThe object that will be merged into the first.\n* `objectN` *Object* (Optional)  \nMore objects to merge into the first.\n\n## License\n\n`node-extend` is licensed under the [MIT License][4].\n\n## Acknowledgements\n\nAll credit to the jQuery authors for perfecting this amazing utility.\n\nPorted to Node.js by [Stefan Thomas][5] with contributions by [Jonathan Buchanan][6] and [Jordan Harband][7].\n\n[1]: https://travis-ci.org/justmoon/node-extend.png\n[2]: https://travis-ci.org/justmoon/node-extend\n[3]: https://npmjs.org/package/extend\n[4]: http://opensource.org/licenses/MIT\n[5]: https://github.com/justmoon\n[6]: https://github.com/insin\n[7]: https://github.com/ljharb\n[8]: http://vb.teelaun.ch/justmoon/node-extend.svg\n[9]: https://david-dm.org/justmoon/node-extend.png\n[10]: https://david-dm.org/justmoon/node-extend\n[11]: https://david-dm.org/justmoon/node-extend/dev-status.png\n[12]: https://david-dm.org/justmoon/node-extend#info=devDependencies\n\n",

+Browser-friendly inheritance fully compatible with standard node.js
+[inherits](http://nodejs.org/api/util.html#util_util_inherits_constructor_superconstructor).
+
+This package exports standard `inherits` from node.js `util` module in
+node environment, but also provides alternative browser-friendly
+implementation through [browser
+field](https://gist.github.com/shtylman/4339901). Alternative
+implementation is a literal copy of standard one located in standalone
+module to avoid requiring of `util`. It also has a shim for old
+browsers with no `Object.create` support.
+
+While keeping you sure you are using standard `inherits`
+implementation in node.js environment, it allows bundlers such as
+[browserify](https://github.com/substack/node-browserify) to not
+include full `util` package to your client code if all you need is
+just `inherits` function. It worth, because browser shim for `util`
+package is large and `inherits` is often the single function you need
+from it.
+
+It's recommended to use this package instead of
+`require('util').inherits` for any code that has chances to be used
+not only in node.js but in browser too.
+
+## usage
+
+```js
+var inherits = require('inherits');
+// then use exactly as the standard one
+```
+
+## note on version ~1.0
+
+Version ~1.0 had completely different motivation and is not compatible
+neither with 2.0 nor with standard node.js `inherits`.
+
+If you are using version ~1.0 and planning to switch to ~2.0, be
+careful:
+
+* new version uses `super_` instead of `super` for referencing
+  superclass
+* new version overwrites current prototype while old one preserves any
+  existing fields on it

It uses the `minimatch`\nlibrary to do its matching.\n\n## Attention: node-glob users!\n\nThe API has changed dramatically between 2.x and 3.x. This library is\nnow 100% JavaScript, and the integer flags have been replaced with an\noptions object.\n\nAlso, there's an event emitter class, proper tests, and all the other\nthings you've come to expect from node modules.\n\nAnd best of all, no compilation!\n\n## Usage\n\n```javascript\nvar glob = require(\"glob\")\n\n// options is optional\nglob(\"**/*.js\", options, function (er, files) {\n  // files is an array of filenames.\n  // If the `nonull` option is set, and nothing\n  // was found, then files is [\"**/*.js\"]\n  // er is an error object or null.\n})\n```\n\n## Features\n\nPlease see the [minimatch\ndocumentation](https://github.com/isaacs/minimatch) for more details.\n\nSupports these glob features:\n\n* Brace Expansion\n* Extended glob matching\n* \"Globstar\" `**` matching\n\nSee:\n\n* `man sh`\n* `man bash`\n* `man 3 fnmatch`\n* `man 5 gitignore`\n* [minimatch documentation](https://github.com/isaacs/minimatch)\n\n## glob(pattern, [options], cb)\n\n* `pattern` {String} Pattern to be matched\n* `options` {Object}\n* `cb` {Function}\n  * `err` {Error | null}\n  * `matches` {Array<String>} filenames found matching the pattern\n\nPerform an asynchronous glob search.\n\n## glob.sync(pattern, [options])\n\n* `pattern` {String} Pattern to be matched\n* `options` {Object}\n* return: {Array<String>} filenames found matching the pattern\n\nPerform a synchronous glob search.\n\n## Class: glob.Glob\n\nCreate a Glob object by instanting the `glob.Glob` class.\n\n```javascript\nvar Glob = require(\"glob\").Glob\nvar mg = new Glob(pattern, options, cb)\n```\n\nIt's an EventEmitter, and starts walking the filesystem to find matches\nimmediately.\n\n### new glob.Glob(pattern, [options], [cb])\n\n* `pattern` {String} pattern to search for\n* `options` {Object}\n* `cb` {Function} Called when an error occurs, or matches are found\n  * `err` {Error | null}\n  * `matches` {Array<String>} filenames found matching the pattern\n\nNote that if the `sync` flag is set in the options, then matches will\nbe immediately available on the `g.found` member.\n\n### Properties\n\n* `minimatch` The minimatch object that the glob uses.\n* `options` The options object passed in.\n* `error` The error encountered.  When an error is encountered, the\n  glob object is in an undefined state, and should be discarded.\n* `aborted` Boolean which is set to true when calling `abort()`.  There\n  is no way at this time to continue a glob search after aborting, but\n  you can re-use the statCache to avoid having to duplicate syscalls.\n* `statCache` Collection of all the stat results the glob search\n  performed.\n* `cache` Convenience object.  Each field has the following possible\n  values:\n  * `false` - Path does not exist\n  * `true` - Path exists\n  * `1` - Path exists, and is not a directory\n  * `2` - Path exists, and is a directory\n  * `[file, entries, ...]` - Path exists, is a directory, and the\n    array value is the results of `fs.readdir`\n\n### Events\n\n* `end` When the matching is finished, this is emitted with all the\n  matches found.  If the `nonull` option is set, and no match was found,\n  then the `matches` list contains the original pattern.  The matches\n  are sorted, unless the `nosort` flag is set.\n* `match` Every time a match is found, this is emitted with the matched.\n* `error` Emitted when an unexpected error is encountered, or whenever\n  any fs error occurs if `options.strict` is set.\n* `abort` When `abort()` is called, this event is raised.\n\n### Methods\n\n* `abort` Stop the search.\n\n### Options\n\nAll the options that can be passed to Minimatch can also be passed to\nGlob to change pattern matching behavior.  Also, some have been added,\nor have glob-specific ramifications.\n\nAll options are false by default, unless otherwise noted.\n\nAll options are added to the glob object, as well.\n\n* `cwd` The current working directory in which to search.  Defaults\n  to `process.cwd()`.\n* `root` The place where patterns starting with `/` will be mounted\n  onto.  Defaults to `path.resolve(options.cwd, \"/\")` (`/` on Unix\n  systems, and `C:\\` or some such on Windows.)\n* `dot` Include `.dot` files in normal matches and `globstar` matches.\n  Note that an explicit dot in a portion of the pattern will always\n  match dot files.\n* `nomount` By default, a pattern starting with a forward-slash will be\n  \"mounted\" onto the root setting, so that a valid filesystem path is\n  returned.  Set this flag to disable that behavior.\n* `mark` Add a `/` character to directory matches.  Note that this\n  requires additional stat calls.\n* `nosort` Don't sort the results.\n* `stat` Set to true to stat *all* results.  This reduces performance\n  somewhat, and is completely unnecessary, unless `readdir` is presumed\n  to be an untrustworthy indicator of file existence.  It will cause\n  ELOOP to be triggered one level sooner in the case of cyclical\n  symbolic links.\n* `silent` When an unusual error is encountered\n  when attempting to read a directory, a warning will be printed to\n  stderr.  Set the `silent` option to true to suppress these warnings.\n* `strict` When an unusual error is encountered\n  when attempting to read a directory, the process will just continue on\n  in search of other matches.  Set the `strict` option to raise an error\n  in these cases.\n* `cache` See `cache` property above.  Pass in a previously generated\n  cache object to save some fs calls.\n* `statCache` A cache of results of filesystem information, to prevent\n  unnecessary stat calls.  While it should not normally be necessary to\n  set this, you may pass the statCache from one glob() call to the\n  options object of another, if you know that the filesystem will not\n  change between calls.  (See \"Race Conditions\" below.)\n* `sync` Perform a synchronous glob search.\n* `nounique` In some cases, brace-expanded patterns can result in the\n  same file showing up multiple times in the result set.  By default,\n  this implementation prevents duplicates in the result set.\n  Set this flag to disable that behavior.\n* `nonull` Set to never return an empty set, instead returning a set\n  containing the pattern itself.  This is the default in glob(3).\n* `nocase` Perform a case-insensitive match.  Note that case-insensitive\n  filesystems will sometimes result in glob returning results that are\n  case-insensitively matched anyway, since readdir and stat will not\n  raise an error.\n* `debug` Set to enable debug logging in minimatch and glob.\n* `globDebug` Set to enable debug logging in glob, but not minimatch.\n\n## Comparisons to other fnmatch/glob implementations\n\nWhile strict compliance with the existing standards is a worthwhile\ngoal, some discrepancies exist between node-glob and other\nimplementations, and are intentional.\n\nIf the pattern starts with a `!` character, then it is negated.  Set the\n`nonegate` flag to suppress this behavior, and treat leading `!`\ncharacters normally.  This is perhaps relevant if you wish to start the\npattern with a negative extglob pattern like `!(a|B)`.  Multiple `!`\ncharacters at the start of a pattern will negate the pattern multiple\ntimes.\n\nIf a pattern starts with `#`, then it is treated as a comment, and\nwill not match anything.  Use `\\#` to match a literal `#` at the\nstart of a line, or set the `nocomment` flag to suppress this behavior.\n\nThe double-star character `**` is supported by default, unless the\n`noglobstar` flag is set.  This is supported in the manner of bsdglob\nand bash 4.1, where `**` only has special significance if it is the only\nthing in a path part.  That is, `a/**/b` will match `a/x/y/b`, but\n`a/**b` will not.\n\nIf an escaped pattern has no matches, and the `nonull` flag is set,\nthen glob returns the pattern as-provided, rather than\ninterpreting the character escapes.  For example,\n`glob.match([], \"\\\\*a\\\\?\")` will return `\"\\\\*a\\\\?\"` rather than\n`\"*a?\"`.  This is akin to setting the `nullglob` option in bash, except\nthat it does not resolve escaped pattern characters.\n\nIf brace expansion is not disabled, then it is performed before any\nother interpretation of the glob pattern.  Thus, a pattern like\n`+(a|{b),c)}`, which would not be valid in bash or zsh, is expanded\n**first** into the set of `+(a|b)` and `+(a|c)`, and those patterns are\nchecked for validity.  Since those two are valid, matching proceeds.\n\n## Windows\n\n**Please only use forward-slashes in glob expressions.**\n\nThough windows uses either `/` or `\\` as its path separator, only `/`\ncharacters are used by this glob implementation.  You must use\nforward-slashes **only** in glob expressions.  Back-slashes will always\nbe interpreted as escape characters, not path separators.\n\nResults from absolute patterns such as `/foo/*` are mounted onto the\nroot setting using `path.join`.  On windows, this will by default result\nin `/foo/*` matching `C:\\foo\\bar.txt`.\n\n## Race Conditions\n\nGlob searching, by its very nature, is susceptible to race conditions,\nsince it relies on directory walking and such.\n\nAs a result, it is possible that a file that exists when glob looks for\nit may have been deleted or modified by the time it returns the result.\n\nAs part of its internal implementation, this program caches all stat\nand readdir calls that it makes, in order to cut down on system\noverhead.  However, this also makes it even more susceptible to races,\nespecially if the cache or statCache objects are reused between glob\ncalls.\n\nUsers are thus advised not to use a glob result as a guarantee of\nfilesystem state in the face of rapid changes.  For the vast majority\nof operations, this is never a problem.\n",

+# Lo-Dash v2.4.1
+A utility library delivering consistency, [customization](http://lodash.com/custom-builds), [performance](http://lodash.com/benchmarks), & [extras](http://lodash.com/#features).
+
+## Download
+
+Check out our [wiki]([https://github.com/lodash/lodash/wiki/build-differences]) for details over the differences between builds.
+
+* Modern builds perfect for newer browsers/environments:<br>
+[Development](https://raw.github.com/lodash/lodash/2.4.1/dist/lodash.js) &
+[Production](https://raw.github.com/lodash/lodash/2.4.1/dist/lodash.min.js)
+
+* Compatibility builds for older environment support too:<br>
+[Development](https://raw.github.com/lodash/lodash/2.4.1/dist/lodash.compat.js) &
+[Production](https://raw.github.com/lodash/lodash/2.4.1/dist/lodash.compat.min.js)
+
+* Underscore builds to use as a drop-in replacement:<br>
+[Development](https://raw.github.com/lodash/lodash/2.4.1/dist/lodash.underscore.js) &
+[Production](https://raw.github.com/lodash/lodash/2.4.1/dist/lodash.underscore.min.js)
+
+CDN copies are available on [cdnjs](http://cdnjs.com/libraries/lodash.js/) & [jsDelivr](http://www.jsdelivr.com/#!lodash). For smaller file sizes, create [custom builds](http://lodash.com/custom-builds) with only the features needed.

+
+## Installation & usage
+
+In browsers:
+
+```html
+<script src="lodash.js"></script>
+```
+
+Using [`npm`](http://npmjs.org/):
+
+```bash
+npm i --save lodash
+
+{sudo} npm i -g lodash
+npm ln lodash
+```
+
+In [Node.js](http://nodejs.org/) & [Ringo](http://ringojs.org/):
+
+```js
+var _ = require('lodash');
+// or as Underscore
+var _ = require('lodash/dist/lodash.underscore');
+```
+
+**Notes:**
+ * Don’t assign values to [special variable](http://nodejs.org/api/repl.html#repl_repl_features) `_` when in the REPL
+ * If Lo-Dash is installed globally, run [`npm ln lodash`](http://blog.nodejs.org/2011/03/23/npm-1-0-global-vs-local-installation/) in your project’s root directory *before* requiring it
+
+In [Rhino](http://www.mozilla.org/rhino/):
+
+```js
+load('lodash.js');
+```
+
+In an AMD loader:
+
+```js
+require({
+  'packages': [
+    { 'name': 'lodash', 'location': 'path/to/lodash', 'main': 'lodash' }
+  ]
+},
+['lodash'], function(_) {
+  console.log(_.VERSION);
+});
+```

1.9.2, RingoJS 0.9, & Rhino 1.7RC5.<br>\nAutomated browser test results [are available](https://saucelabs.com/u/lodash) as well as [Travis CI](https://travis-ci.org/) builds for [lodash](https://travis-ci.org/lodash/lodash/), [lodash-cli](https://travis-ci.org/lodash/lodash-cli/), [lodash-amd](https://travis-ci.org/lodash/lodash-amd/), [lodash-node](https://travis-ci.org/lodash/lodash-node/), & [grunt-lodash](https://travis-ci.org/lodash/grunt-lodash).\n\nSpecial thanks to [Sauce Labs](https://saucelabs.com/) for providing automated browser testing.<br>\n[![Sauce Labs](http://lodash.com/_img/sauce.png)](https://saucelabs.com/ \"Sauce Labs: Selenium Testing & More\")\n\n## Installation & usage\n\nIn browsers:\n\n```html\n<script src=\"lodash.js\"></script>\n```\n\nUsing [`npm`](http://npmjs.org/):\n\n```bash\nnpm i --save lodash\n\n{sudo} npm i -g lodash\nnpm ln lodash\n```\n\nIn [Node.js](http://nodejs.org/) & [Ringo](http://ringojs.org/):\n\n```js\nvar _ = require('lodash');\n// or as Underscore\nvar _ = require('lodash/dist/lodash.underscore');\n```\n\n**Notes:**\n * Don’t assign values to [special variable](http://nodejs.org/api/repl.html#repl_repl_features) `_` when in the REPL\n * If Lo-Dash is installed globally, run [`npm ln lodash`](http://blog.nodejs.org/2011/03/23/npm-1-0-global-vs-local-installation/) in your project’s root directory *before* requiring it\n\nIn [Rhino](http://www.mozilla.org/rhino/):\n\n```js\nload('lodash.js');\n```\n\nIn an AMD loader:\n\n```js\nrequire({\n  'packages': [\n    { 'name': 'lodash', 'location': 'path/to/lodash', 'main': 'lodash' }\n  ]\n},\n['lodash'], function(_) {\n  console.log(_.VERSION);\n});\n```\n\n## Author\n\n|

Or just filenames.\n\n### minimatchOptions\nType: `Object`  \nDefault: `{}`\n\nOptions to be passed to [minimatch](https://github.com/isaacs/minimatch).\n\nNote that if you want to start in a different directory than the current working directory, specify a `cwd` property here.\n\n## Contributing\nIn lieu of a formal styleguide, take care to maintain the existing coding style.

Let's call it [hacker](http://github.com/tkellen/node-hacker).  You want to configure it using a `Hackerfile`.  This is node, so you install `hacker` locally for each project you use it in.  But, in order to get the `hacker` command in your PATH, you also install it globally.\n\nNow, when you run the `hacker` command, you want it to use the `Hackerfile` in your current directory, and the local installation of `hacker` next to it.  It'd be nice if it traversed up your folders until it found a `Hackerfile`&mdash;for those times when you're not in the root directory of your project.  Heck, you might even want to launch it from a folder outside of your project by manually specifying a working directory.  Liftoff manages this for you.\n\nSo, everything is working great.  Now you can find your local `hacker` and `Hackerfile` with ease.  Unfortunately, it turns out you've authored your `Hackerfile` in coffee-script, or some other JS variant.  In order to support *that*, you have to load the compiler for it, and then register the extension for it with node.  Good news, Liftoff can do that too.\n\n## API\n\n### constructor(opts)\n\nCreate an instance of Liftoff to invoke your application.\n\nAn example utilizing all options:\n```js\nvar Hacker = new Liftoff({\n  name: 'hacker',\n  moduleName: 'hacker',\n  configName: 'hackerfile',\n  addExtensions: ['.anything'],\n  processTitle: 'hacker',\n  cwdFlag: 'cwd',\n  configPathFlag: 'hackerfile',\n  preloadFlag: 'require',\n  completionFlag: 'completion',\n  completions: function (type) {\n    console.log('Completions not implemented.');\n  }\n});\n```\n\n#### opts.name\n\nSugar for setting `processTitle`, `moduleName`, `configName` & `configPathFlag` automatically.\n\nType: `String`\nDefault: `null`\n\nThese are equivalent:\n```js\nnew Liftoff({\n  processTitle: 'hacker',\n  moduleName: 'hacker',\n  configName: 'hackerfile',\n  configPathFlag: 'hackerfile'\n});\n```\n```js\nnew Liftoff({name:'hacker'});\n```\n\n#### opts.moduleName\n\nSets which module your application expects to find locally when being run.\n\nType: `String`\nDefault: `null`\n\n#### opts.configName\n\nSets the name of the configuration file Liftoff will attempt to find.  Case-insensitive.\n\nType: `String`\nDefault: `null`\n\n#### opts.addExtensions\n\nExplicitly add custom extensions to include when searching for a configuration file.  Node supports `.js`, `.json` & `.node` natively, so there is no need to add these.\n\nAn example usage for this setting would be to add an `rc` extension.  e.g. with a configName of `.myapp`, you want Liftoff to look for `.myapp{rc,.js,.json,.node}`\n\nType: `Array`\nDefault: `[]`\n\n#### opts.processTitle\n\nSets what the [process title](http://nodejs.org/api/process.html#process_process_title) will be.\n\nType: `String`\nDefault: `null`\n\n#### opts.cwdFlag\n\nSets what flag to use for altering the current working directory.  For example, `myapp --cwd ../` would invoke your application as though you'd called it from the parent of your current directory.\n\nType: `String`\nDefault: `cwd`\n\n#### opts.configPathFlag\n\nSets what flag to use for defining the path to your configfile.  For example, `myapp --myappfile ../Myappfile.js` would explicitly specify the location of your config file.\n\nType: `String`\nDefault: `same as configName`\n\n#### opts.modulePathFlag\n\nSets what flag to use for defining the path to your locally installed module.  For example, `myapp --myappdir ~/` would specify the location of your config file.  This option overrides `cwdFlag`.\n\nType: `String`\nDefault: `same as configName`\n\n#### opts.preloadFlag\n\nSets what flag to use for pre-loading modules.  For example, `myapp --require coffee-script` would require a local version of coffee-script (if available) before attempting to find your configuration file.  If your required module registers a new\n[require.extension](http://nodejs.org/api/globals.html#globals_require_extensions), it will be included as an option when looking for a file matching `configName`.\n\nType: `String`\nDefault: `\"require\"`\n\n#### opts.completions(type)\n\nA method to handle bash/zsh/whatever completions.\n\nType: `Function`\nDefault: `null`\n\n### events\n\n#### require(name, module)\n\nEmitted when a module is pre-loaded.\n\n```js\nvar Hacker = new Liftoff({name:'hacker'});\nHacker.on('require', function (name, module) {\n  console.log('Requiring external module: '+name+'...');\n  // automatically register coffee-script extensions\n  if (name === 'coffee-script') {\n    module.register();\n  }\n});\n```\n\n#### requireFail(name, err)\n\nEmitted when a requested module cannot be preloaded.\n\n```js\nvar Hacker = new Liftoff({name:'hacker'});\nHacker.on('requireFail', function (name, err) {\n  console.log('Unable to load:', name, err);\n});\n```\n\n### launch(fn, argv)\n\n#### fn(env)\n\nA function to start your application.  When invoked, `this` will be your instance of Liftoff.  The `env` param will contain the following keys:\n\n- `argv`: cli arguments, as parsed by [minimist](https://npmjs.org/package/minimist), or as passed in manually.\n- `cwd`: the current working directory\n- `preload`: an array of modules that liftoff tried to pre-load\n- `validExtensions`: an array of supported extensions for your config file\n- `configNameRegex`: the regular expression used to find your config file\n- `configPath`: the full path to your configuration file (if found)\n- `configBase`: the base directory of your configuration file (if found)\n- `modulePath`: the full path to the local module your project relies on (if found)\n- `modulePackage`: the contents of the local module's package.json (if found)\n\n#### argv\nManually specify command line arguments.  Useful for invoking the CLI programmatically.\n\nType: `Object`\nDefault: `null`\n\n## Examples\nCheck out [the hacker project](https://github.com/tkellen/node-hacker/blob/master/bin/hacker.js) to see a working example of this tool.\n\nTo try the example, do the following:\n\n1. Install the sample project `hacker` with `npm install -g hacker`.\n2. Make a `Hackerfile.js` with some arbitrary javascript it.\n3. Install hacker next to it with `npm install hacker`.\n3. Run `hacker` while in the same parent folder.\n\nFor extra credit, try writing your `Hackerfile` in coffeescript.  Then, run `hacker --require coffee-script`.  Make sure you install coffee-script locally, though.\n",

It uses the `minimatch`\nlibrary to do its matching.\n\n## Attention: node-glob users!\n\nThe API has changed dramatically between 2.x and 3.x. This library is\nnow 100% JavaScript, and the integer flags have been replaced with an\noptions object.\n\nAlso, there's an event emitter class, proper tests, and all the other\nthings you've come to expect from node modules.\n\nAnd best of all, no compilation!\n\n## Usage\n\n```javascript\nvar glob = require(\"glob\")\n\n// options is optional\nglob(\"**/*.js\", options, function (er, files) {\n  // files is an array of filenames.\n  // If the `nonull` option is set, and nothing\n  // was found, then files is [\"**/*.js\"]\n  // er is an error object or null.\n})\n```\n\n## Features\n\nPlease see the [minimatch\ndocumentation](https://github.com/isaacs/minimatch) for more details.\n\nSupports these glob features:\n\n* Brace Expansion\n* Extended glob matching\n* \"Globstar\" `**` matching\n\nSee:\n\n* `man sh`\n* `man bash`\n* `man 3 fnmatch`\n* `man 5 gitignore`\n* [minimatch documentation](https://github.com/isaacs/minimatch)\n\n## glob(pattern, [options], cb)\n\n* `pattern` {String} Pattern to be matched\n* `options` {Object}\n* `cb` {Function}\n  * `err` {Error | null}\n  * `matches` {Array<String>} filenames found matching the pattern\n\nPerform an asynchronous glob search.\n\n## glob.sync(pattern, [options])\n\n* `pattern` {String} Pattern to be matched\n* `options` {Object}\n* return: {Array<String>} filenames found matching the pattern\n\nPerform a synchronous glob search.\n\n## Class: glob.Glob\n\nCreate a Glob object by instanting the `glob.Glob` class.\n\n```javascript\nvar Glob = require(\"glob\").Glob\nvar mg = new Glob(pattern, options, cb)\n```\n\nIt's an EventEmitter, and starts walking the filesystem to find matches\nimmediately.\n\n### new glob.Glob(pattern, [options], [cb])\n\n* `pattern` {String} pattern to search for\n* `options` {Object}\n* `cb` {Function} Called when an error occurs, or matches are found\n  * `err` {Error | null}\n  * `matches` {Array<String>} filenames found matching the pattern\n\nNote that if the `sync` flag is set in the options, then matches will\nbe immediately available on the `g.found` member.\n\n### Properties\n\n* `minimatch` The minimatch object that the glob uses.\n* `options` The options object passed in.\n* `error` The error encountered.  When an error is encountered, the\n  glob object is in an undefined state, and should be discarded.\n* `aborted` Boolean which is set to true when calling `abort()`.  There\n  is no way at this time to continue a glob search after aborting, but\n  you can re-use the statCache to avoid having to duplicate syscalls.\n* `statCache` Collection of all the stat results the glob search\n  performed.\n* `cache` Convenience object.  Each field has the following possible\n  values:\n  * `false` - Path does not exist\n  * `true` - Path exists\n  * `1` - Path exists, and is not a directory\n  * `2` - Path exists, and is a directory\n  * `[file, entries, ...]` - Path exists, is a directory, and the\n    array value is the results of `fs.readdir`\n\n### Events\n\n* `end` When the matching is finished, this is emitted with all the\n  matches found.  If the `nonull` option is set, and no match was found,\n  then the `matches` list contains the original pattern.  The matches\n  are sorted, unless the `nosort` flag is set.\n* `match` Every time a match is found, this is emitted with the matched.\n* `error` Emitted when an unexpected error is encountered, or whenever\n  any fs error occurs if `options.strict` is set.\n* `abort` When `abort()` is called, this event is raised.\n\n### Methods\n\n* `abort` Stop the search.\n\n### Options\n\nAll the options that can be passed to Minimatch can also be passed to\nGlob to change pattern matching behavior.  Also, some have been added,\nor have glob-specific ramifications.\n\nAll options are false by default, unless otherwise noted.\n\nAll options are added to the glob object, as well.\n\n* `cwd` The current working directory in which to search.  Defaults\n  to `process.cwd()`.\n* `root` The place where patterns starting with `/` will be mounted\n  onto.  Defaults to `path.resolve(options.cwd, \"/\")` (`/` on Unix\n  systems, and `C:\\` or some such on Windows.)\n* `dot` Include `.dot` files in normal matches and `globstar` matches.\n  Note that an explicit dot in a portion of the pattern will always\n  match dot files.\n* `nomount` By default, a pattern starting with a forward-slash will be\n  \"mounted\" onto the root setting, so that a valid filesystem path is\n  returned.  Set this flag to disable that behavior.\n* `mark` Add a `/` character to directory matches.  Note that this\n  requires additional stat calls.\n* `nosort` Don't sort the results.\n* `stat` Set to true to stat *all* results.  This reduces performance\n  somewhat, and is completely unnecessary, unless `readdir` is presumed\n  to be an untrustworthy indicator of file existence.  It will cause\n  ELOOP to be triggered one level sooner in the case of cyclical\n  symbolic links.\n* `silent` When an unusual error is encountered\n  when attempting to read a directory, a warning will be printed to\n  stderr.  Set the `silent` option to true to suppress these warnings.\n* `strict` When an unusual error is encountered\n  when attempting to read a directory, the process will just continue on\n  in search of other matches.  Set the `strict` option to raise an error\n  in these cases.\n* `cache` See `cache` property above.  Pass in a previously generated\n  cache object to save some fs calls.\n* `statCache` A cache of results of filesystem information, to prevent\n  unnecessary stat calls.  While it should not normally be necessary to\n  set this, you may pass the statCache from one glob() call to the\n  options object of another, if you know that the filesystem will not\n  change between calls.  (See \"Race Conditions\" below.)\n* `sync` Perform a synchronous glob search.\n* `nounique` In some cases, brace-expanded patterns can result in the\n  same file showing up multiple times in the result set.  By default,\n  this implementation prevents duplicates in the result set.\n  Set this flag to disable that behavior.\n* `nonull` Set to never return an empty set, instead returning a set\n  containing the pattern itself.  This is the default in glob(3).\n* `nocase` Perform a case-insensitive match.  Note that case-insensitive\n  filesystems will sometimes result in glob returning results that are\n  case-insensitively matched anyway, since readdir and stat will not\n  raise an error.\n* `debug` Set to enable debug logging in minimatch and glob.\n* `globDebug` Set to enable debug logging in glob, but not minimatch.\n\n## Comparisons to other fnmatch/glob implementations\n\nWhile strict compliance with the existing standards is a worthwhile\ngoal, some discrepancies exist between node-glob and other\nimplementations, and are intentional.\n\nIf the pattern starts with a `!` character, then it is negated.  Set the\n`nonegate` flag to suppress this behavior, and treat leading `!`\ncharacters normally.  This is perhaps relevant if you wish to start the\npattern with a negative extglob pattern like `!(a|B)`.  Multiple `!`\ncharacters at the start of a pattern will negate the pattern multiple\ntimes.\n\nIf a pattern starts with `#`, then it is treated as a comment, and\nwill not match anything.  Use `\\#` to match a literal `#` at the\nstart of a line, or set the `nocomment` flag to suppress this behavior.\n\nThe double-star character `**` is supported by default, unless the\n`noglobstar` flag is set.  This is supported in the manner of bsdglob\nand bash 4.1, where `**` only has special significance if it is the only\nthing in a path part.  That is, `a/**/b` will match `a/x/y/b`, but\n`a/**b` will not.\n\nIf an escaped pattern has no matches, and the `nonull` flag is set,\nthen glob returns the pattern as-provided, rather than\ninterpreting the character escapes.  For example,\n`glob.match([], \"\\\\*a\\\\?\")` will return `\"\\\\*a\\\\?\"` rather than\n`\"*a?\"`.  This is akin to setting the `nullglob` option in bash, except\nthat it does not resolve escaped pattern characters.\n\nIf brace expansion is not disabled, then it is performed before any\nother interpretation of the glob pattern.  Thus, a pattern like\n`+(a|{b),c)}`, which would not be valid in bash or zsh, is expanded\n**first** into the set of `+(a|b)` and `+(a|c)`, and those patterns are\nchecked for validity.  Since those two are valid, matching proceeds.\n\n## Windows\n\n**Please only use forward-slashes in glob expressions.**\n\nThough windows uses either `/` or `\\` as its path separator, only `/`\ncharacters are used by this glob implementation.  You must use\nforward-slashes **only** in glob expressions.  Back-slashes will always\nbe interpreted as escape characters, not path separators.\n\nResults from absolute patterns such as `/foo/*` are mounted onto the\nroot setting using `path.join`.  On windows, this will by default result\nin `/foo/*` matching `C:\\foo\\bar.txt`.\n\n## Race Conditions\n\nGlob searching, by its very nature, is susceptible to race conditions,\nsince it relies on directory walking and such.\n\nAs a result, it is possible that a file that exists when glob looks for\nit may have been deleted or modified by the time it returns the result.\n\nAs part of its internal implementation, this program caches all stat\nand readdir calls that it makes, in order to cut down on system\noverhead.  However, this also makes it even more susceptible to races,\nespecially if the cache or statCache objects are reused between glob\ncalls.\n\nUsers are thus advised not to use a glob result as a guarantee of\nfilesystem state in the face of rapid changes.  For the vast majority\nof operations, this is never a problem.\n",

This means we promote solid browser/environment support, ES5 precedents, unit testing, and plenty of documentation.\n\n## Author\n\n| [![twitter/jdalton](http://gravatar.com/avatar/299a3d891ff1920b69c364d061007043?s=70)](http://twitter.com/jdalton \"Follow @jdalton on Twitter\") |\n|---|\n| [John-David Dalton](http://allyoucanleet.com/) |\n\n## Contributors\n\n| [![twitter/blainebublitz](http://gravatar.com/avatar/ac1c67fd906c9fecd823ce302283b4c1?s=70)](http://twitter.com/blainebublitz \"Follow @BlaineBublitz on Twitter\") | [![twitter/kitcambridge](http://gravatar.com/avatar/6662a1d02f351b5ef2f8b4d815804661?s=70)](https://twitter.com/kitcambridge \"Follow @kitcambridge on Twitter\") | [![twitter/mathias](http://gravatar.com/avatar/24e08a9ea84deb17ae121074d0f17125?s=70)](http://twitter.com/mathias \"Follow @mathias on Twitter\") |\n|---|---|---|\n| [Blaine Bublitz](http://iceddev.com/) | [Kit Cambridge](http://kitcambridge.github.io/) | [Mathias Bynens](http://mathiasbynens.be/) |\n",
