== About texvc ==
-texvc takes LaTeX-compatible equations and produces formatted output in
-HTML, MathML, and (via LaTeX/dvips/ImageMagick) rasterized PNG images.
-Input data is parsed and scrutinized for safety, and the output includes
-an estimate of whether the code is simple enough that HTML rendering will
-look acceptable.

== Setup ==
=== Requirements ===
-OCaml 3.06 or later is required to compile texvc; this can be acquired
-from http://caml.inria.fr/ if your system doesn't have it available.

The makefile requires GNU make.
-Rasterization is done via LaTeX, dvips, and ImageMagick. These need
-to be installed and in the PATH: latex, dvips, convert

-AMS* packages for LaTeX also need to be installed. Without AMS* some
-equations will render correctly while others won't render.
-Most distributions of TeX already contain AMS*.
-In Debian/Ubuntu you need to install tetex-extra.

=== Installation ===
Run 'make' (or 'gmake' if GNU make is not your default make). This should
produce the texvc executable.
-If you're using MediaWiki's install.php and have enabled $wgUseTeX in your
-LocalSettings.php, the installer will try to copy texvc into place, in the
-'math' subdirectory under where wiki.phtml is installed.
-
+Then you'll need to set $wgUseTeX to true in your LocalSettings.php. By default,
+MediaWiki will search in this directory for texvc, if you moved it elsewhere,
+you'll have to modify $wgTexvc and set it to the path of the texvc executable.
== Usage ==
2. texvc does its magic, which is basically to check for invalid latex code.
3. texvc takes the user input if valid and creates a latex file containing it, see
get_preface in texutil.ml
-4. latex(1) gets called to create a .dvi file, then a .ps file is created from the
- .dvi file using dvips(1), and finally convert(1) creates a .png file from
- the .ps file. See render.ml for this process (commenting out the removal of

the temporary file is useful for debugging).
