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 the program hyperlatex to produce good-quality HTML. HyperLaTeX is not a LaTeX to HTML converter (see, for example, tth or latex2html for that). Rather, HyperLaTeX provides an environment where the author can prepare a document that may be converted to either print or HTML output.
