A number of the functions described in Section 7
involve commands which can be embedded in the LaTeX source
file (ie the *.tex file) which are defined in the
html.sty file supplied with the latex2html package.

MUST be included as a argument of the \documentstyle
command at the top of the LaTeX file.
For example, the first line of this document is:
\documentstyle[11pt,html]{article}
