HyperLaTeX defines a form of LaTeX that may be processed in the ordinary way with a 'latex' command, for printed output. However, HyperLaTeX documents may also be processed by 'hyperlatex', to produce good-quality HTML.

HyperLaTeX is not a LaTeX to HTML converter (see tth or latex2html for that). Rather, HyperLaTeX specifies a language that can be processed as if it were LaTeX, but which can also be processed to HTML. The authors are Tom Sgouros and Otfried Cheong.
