Nevertheless, on TeX files that are predominantly text and use standard constructs and macros, the results are rather satisfactory. LaTeX has its own translator, latex2html, which is recommended for LaTeX code. Conversion of even large TeX files should be a matter of a second or two. It is freely distributed. But not from the implicit texinputs path.
All definitions are global.
Equations are, by default, translated internally into HTML3.2 as much as it allows, which is not all that much, since HTML3.2 has virtually no support for symbols, greek, and so on. Roughly speaking, superscripts, subscripts, and latin characters are supported. Untranslatable TeX math tokens are inserted verbatim. This last fact makes the alternate translation generally less useful. Moreover, you have to get the program math2html yourself and install it.
