Conditional text can be specified using the environments latexonly and htmlonly. These allow writing parts of a document which are intended only for electronic delivery or only for paper-based delivery.
This would be useful for example in adding a long description of a multimedia resource in the paper version of a document. Such a description would be redundant in the electronic version, as the user can have direct access to this resource.
Here is an example of the use of the latexonly environment:
There are also shorthand notations to accomplish the same thing
with less typing. The \latex{} command causes everything
within the braces to be processed by LaTeX, but ingored by
LaTeX2HTML. Conversely, the \html{} command causes
everything within the braces to be ignored by LaTeX and
processed by LaTeX2HTML. Finally the command
\latexhtml{}{} causes everthing within the first set
of braces to be processed exclusively by LaTeX, with
the contents of the second set of braces processed solely
by LaTeX2HTML.
