Selectively include/exclude pieces of text, allowing the user
to define new, separately controlled, comment versions. All
text between \comment ... \endcomment or \begin{comment} ...
\end{comment} is discarded. The opening and closing commands
should appear on a line of their own. No starting spaces,
nothing after it. This environment should work with arbitrary
amounts of comment, and the comment can be arbitrary text.
Other 'comment' environments are defined and
selected/deselected with \includecomment{versiona} and
\excludecoment{versionb} These environments are used as
\versiona ... \endversiona or \begin{versiona} ...
\end{versiona} with the opening and closing commands again on a
line of their own.
