FooTex is software for converting LaTeX math markup into MathML, HTML, or PNG. It is basically just a wrapper for texvc and blahtex. It provides some extra functionality, and gives a consistent interface to the functionality of the two underlying packages. The documentation is built into the source code. When you install footex, the documentation will be installed as a man page.
Release Notes: Conversion of align environments is improved. A newer version of blahtex is packaged with this version of footex.
