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.
