##        Mod title:  punLaTeX

##           Author:  Chris Moore (chris@ilovephysics.com)
##
##      Description:  Adds support for the LaTeX math mark-up language,
##              allowing equations to be posted in forums.
##
##   Affected files:  include/parser.php
##
##       Affects DB:  No
##
##            Notes:  This mod uses a LaTeX engine called mimeTeX. MimeTeX
##              parses a LaTeX math expression and emits the
##              corresponding gif image on-the-fly. It is a separate
##              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. This means that it can be used on servers that
##              do not have LaTeX installed, such as most free and paid
##              hosting.
##

##                    own risk. Backup your forum database and any and all
##                    applicable files before proceeding.
