II. INTRODUCTION
------------------------------------------------------------------------
MimeTeX is licensed under the gpl. It parses LaTeX math expressions,
emitting either gif images or mime xbitmaps of them, rather than the
usual TeX dvi's. And mimeTeX is an entirely separate little program
that doesn't use TeX in any way. Therefore, mimeTeX images are easily
inserted directly into html documents using a standard html <img> tag,
<img src="../cgi-bin/mimetex.cgi?f(x)=\int_{-\infty}^x~e^{-t^2}dt"
border=0 align=absmiddle>
without intermediate dvi-to-gif conversion, and without storing lots
of little gif image files, one file for each converted expression.
This makes your web site and html documents more easily maintained.

Thus, mimeTeX is primarily intended to help you write native html
documents containing math. In this sense it's a kind of "lightweight"
alternative to MathML, with the advantage that mimeTeX preserves LaTeX
syntax, and works with any browser and server.
MimeTeX, licensed under the gpl, lets you easily embed LaTeX math in
your html pages. It parses a LaTeX math expression and immediately
emits the corresponding gif image, rather than the usual TeX dvi.
And mimeTeX is an entirely separate little program that doesn't
use TeX or its fonts in any way. It's just one cgi that you put in
your site's cgi-bin/ directory, with no other dependencies.
So mimeTeX is very easy to install. And it's equally easy to use.
Just place an html <img> tag in your document wherever you want to
see the corresponding LaTeX expression. For example,
<img src="../cgi-bin/mimetex.cgi?f(x)=\int_{-\infty}^x~e^{-t^2}dt"
border=0 align=absmiddle>
generates and displays the corresponding gif image on-the-fly,
wherever you put that <img> tag. MimeTeX doesn't need intermediate
dvi-to-gif conversion, and it doesn't clutter your filesystem with
separate little gif files for each converted expression. (Optional
image caching does store gif files, and subsequently reads them as
needed, rather than re-rendering the same images every time a page
is reloaded.)

Conversion for Windows, Macs, VMS, etc, can usually be accomplished
with unzip's -a option, i.e., unzip -a mimetex.zip

Now, to produce an executable that emits anti-aliased gif images
(which is how the "official" www.forkosh.com/mimetex.html page
is displayed), compile mimetex with the command
cc -DAA mimetex.c gifsave.c -lm -o mimetex.cgi

Or, to produce an executable that emits gif images
without anti-aliasing, compile mimetex with the command
cc -DGIF mimetex.c gifsave.c -lm -o mimetex.cgi

Alternatively, for an executable that emits mime xbitmaps,
just compile mimetex with the command
cc -DXBITMAP mimetex.c -lm -o mimetex.cgi

Several additional command-line options that you may find
useful are discussed in Section IIc (href="#options")
of mimetex.html .

That's all there is to building mimeTeX. You can now test mimetex.cgi
from the Unix command line by typing, e.g.,
./mimetex.cgi x^2+y^2
which should emit an ascii raster something like the left-hand
illustration. And if you've compiled mimeTeX with the anti-aliasing
-DAA option, then you'll also see the right-hand illustration.
It shows asterisks in the same positions as the left-hand illustration,
and anti-aliased grayscale colormap indexes assigned to neighboring
pixels. And you'll also be shown the actual rgb value for each index.
Now, to compile a mimeTeX executable that emits anti-aliased gif
images (recommended for most uses), type the command
cc -DAA mimetex.c gifsave.c -lm -o mimetex.cgi

Or, for an executable that emits gif images without
anti-aliasing,
cc -DGIF mimetex.c gifsave.c -lm -o mimetex.cgi

Alternatively, to compile a mimeTeX executable that emits
mime xbitmaps, just type the command
cc -DXBITMAP mimetex.c -lm -o mimetex.cgi

Compile Notes:
* If (and only if) you're compiling a Windows executable
with the -DAA or -DGIF option (but not -DXBITMAP), then
add -DWINDOWS also. For example,
cc -DAA -DWINDOWS mimetex.c gifsave.c -lm -o mimetex.cgi
The above Unix-like syntax works with MinGW (http://www.mingw.org)
and djgpp (http://www.delorie.com/djgpp/) Windows compilers, but
probably not with most others, where it's only intended as a
"template".
* Several additional command-line options that you may find
useful are discussed in Section IId (href="#options")
of your mimetex.html page.

That's all there is to building mimeTeX. You can now test your
mimetex.cgi executable from the Unix command line by typing, e.g.,
./mimetex.cgi "x^2+y^2"
which should emit two ascii rasters something like the following
Ascii dump of bitmap image... Hex dump of colormap indexes...
........**..................**.. .......1**1................1**1.
.......*..*.....*..........*..*. .......*23*.....*..........*23*.

If you get much fancier than x^2+y^2, remember that many characters have
to be escaped from the Unix command line, e.g., x\<y or f\(x\)=x^2, etc.
Of course, you won't need these extra escapes when running mimetex from
a browser.

Once mimetex.cgi is working (and you're done playing with it),
mv it to your server's cgi-bin/ directory, where cgi programs
are expected (and chmod/chown it if necessary). Then mv
mimetex.html to your server's htdocs/ directory. Now point
your browser to www.yourdomain.com/mimetex.html , and it should
be rendered exactly like my page at www.forkosh.com/mimetex.html .
One "gotcha": the two directories are typically of the form
somewhere/www/cgi-bin/ and somewhere/www/htdocs/ , so I set up
mimtex.html to get mimetex.cgi from the relative path ../cgi-bin/ .
If your directories are non-conforming, you may have to edit the
few dozen occurrences of ../cgi-bin/mimetex.cgi in mimetex.html
(globally changing ../cgi-bin/mimetex.cgi should work).
Sometimes a suitable symlink works; if not, you'll have to edit.

Either way, once mimetex.html displays properly, and you've reviewed
the tutorial it contains, you can begin writing html documents using
mimetex.cgi to render your math.
The right-hand illustration shows asterisks in the same positions as
the left-hand one, along with anti-aliased grayscale colormap indexes
assigned to neighboring pixels, and with the rgb value for each
index. Just typing ./mimetex.cgi without an argument should produce
ascii rasters for the default expression f(x)=x^2. If you see the
two ascii rasters then your binary's good, so mv it to your server's
cgi-bin/ directory and set permissions as necessary.

Once mimetex.cgi is working, mv it to your server's cgi-bin/ directory
(wherever cgi programs are expected), and chmod/chown it as necessary.
Then mv mimetex.html to your server's htdocs/ directory. Now point
your browser to www.yourdomain.com/mimetex.html and you should see
your mimeTeX user's manual reference page.

Install Notes:
* These two directories are typically of the form
somewhere/www/cgi-bin/ and somewhere/www/htdocs/
so I set up mimtex.html to access mimetex.cgi from
the relative path ../cgi-bin/ If your directories
are non-conforming, you may have to edit the few dozen
occurrences of ../cgi-bin/mimetex.cgi in mimetex.html
Sometimes a suitable symlink works. If not, you'll
have to edit. In that case, globally changing
../cgi-bin/mimetex.cgi often works.
* Either way, once mimetex.html displays properly, you can
assume everything is working, and can begin authoring html
documents using mimetex.cgi to render your own math.
