Facilitate optional printing of parts of a document
Description
Optional provides simple, flexible, optional compilation of
LaTeX documents. Option switches may be given via package
options, by the \UseOption command, or interactively via the
\AskOption command (help text may be provided, by defining the
\ExplainOptions command). The package is not robust, in the way
that comment package is, against ill-behaved text. In
particular, verbatim text may not be directly included in
optional sections (whether they're included or not).
