How to generate <ul> & <li> or \begin{itemize} in documentation?

[Mojca M. <moj...@gm...>]

Dear list,

What is the syntax in help for terminals that would generate
<ul><li>...</li>...</ul> syntax in HTML output, \begin{itemize} in
LaTeX (PDF documentation) and a normal "-" in text mode?

Also, how could one replace TeX with \TeX in gnuplot.tex that is used
to generate gnuplot.doc?

Thank you,
   Mojca
