The texmathml library provides functions to convert LaTeX math formulas
to presentation MathML (which can be used in HTML) or OMML (Office Math
Markup Language, used in Microsoft Office). It supports basic LaTeX and
AMS extensions, and it can parse and apply LaTeX macros.

Use the test flag to install a standalone executable, texmath, that
reads a LaTeX formula from stdin and writes MathML to stdout.

Use the cgi flag to install a cgi script, texmath-cgi.
