LaTeX

LaTeX for zope

first install hevea on your server
if using latest mozilla on linux, use this script to view the htmlized latex in symbol font: http://hutchinson.belmont.ma.us/tth/Xfonts.fix (because mozilla follows standards and symbols font are not an official standard)

Someone else also wrote a latex tag for dtml, I think
tth is non-open-source but renders fractions and square roots better than hevea
