+I'd like to present a standalone command line vanity address generator 
+called vanitygen.
+
+There are plenty of quality tools to do this right now already.  So why 
+use vanitygen?  The main reason is that it is fast, more than an order 
+of magnitude faster than the official bitcoin client with the vanity 
+address patch applied.  This is despite the fact that it runs on the 
+CPU and does not use OpenCL or CUDA.  Vanitygen is also a bit more 
+user-friendly in that it provides feedback on its rate of progress and 
+how many keys it has checked.
+
+Vanitygen is written in C, and is provided in source code form and 
+pre-built Win32 binaries.  At present, vanitygen can be built on Linux, 
+and requires the openssl and pcre libraries.
+
+Vanitygen can generate regular bitcoin addresses, namecoin addresses, 
+and testnet addresses.
+
+Vanitygen can search for exact prefixes or regular expression matches.  
+When searching for exact prefixes, vanitygen will ensure that the 
+prefix is possible, will provide a difficulty estimate, and will run 
+about 30% faster.  Exact prefixes are case-sensitive by default, but 
+may be searched case-insensitively using the "-i" option.  Regular 
+expression patterns follow the Perl-compatible regular expression 
+language.
+
+Vanitygen can accept a list of patterns to search for, either on the 
+command line, or from a file or stdin using the "-f" option.  File 
+sources should have one pattern per line.  When searching for N exact 
+prefixes, performance of O(logN) can be expected, and extremely long 
+lists of prefixes will have little effect on search rate.  Searching 
+for N regular expressions will have varied performance depending on the 
+complexity of the expressions, but O(N) performance can be expected.
+
+By defaut, vanitygen will spawn one worker thread for each CPU in your 
+system.  If you wish to limit the number of worker threads created by 
+vanitygen, use the "-t" option.
+
+The example below completed quicker than average, and took about 45 sec 
+to finish, using both cores of my aging Core 2 Duo E6600:
+
+$ ./vanitygen 1Love
+Difficulty: 4476342
+[48165 K/s][total 2080000][Prob 37.2%][50% in 21.2s]                           
+Pattern: 1Love
+Address: 1LoveRg5t2NCDLUZh6Q8ixv74M5YGVxXaN
+Privkey: 5JLUmjZiirgziDmWmNprPsNx8DYwfecUNk1FQXmDPaoKB36fX1o
+
+Currently, it is difficult to import the private key into bitcoin.  
+Sipa's showwallet branch has a new command called "importprivkey" that 
+accepts the base-58 encoded private key.  Vanitygen has been tested to 
+work with that version of bitcoin.
