+% This is an unmodified version of comment.sty (version 3.2) that is distributed
+% with acrotex under the name of aeb-comment.sty. D. P. Story (dpstory at acrotex dot net)
+%
+% Comment.sty   version 3.2, August 1997
+% selectively in/exclude pieces of text: the user can define new
+% comment versions, and each is controlled separately.
+% Special comments can be defined where the user specifies the
+% action that is to be taken with each comment line.
+%
+% This style can be used with plain TeX or LaTeX, and probably
+% most other packages too.
+%
+% Author
+%    Victor Eijkhout
+%    Department of Mathematics
+%    University of California
+%    405 Hilgard Ave, MS 6363
+%    Los Angeles, CA 90034
+%    USA

+%    eijkhout@math.ucla.edu
+%
+% Usage: all text included in 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.
+%
+% Other `comment' environments are defined by
+% and are selected/deselected with
+% \includecomment{versiona}
+% \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.
+%
+% LaTeX users note: for an included comment, the
+% \begin and \end lines act as if they don't exist.
+% In particular, assignments &c are not local.
+%
+% Special comments are defined as
+% \specialcomment{name}{before commands}{after commands}
+% where the second and third arguments are executed before
+% and after each comment block.
+% By defining a control sequence
+% \Thiscomment##1{...} in the before commands the user can
+% specify what is to be done with each comment line.
+% To keep definitions &c local, you can include \begingroup
+% in the `before commands' and \endgroup in the `after commands'.
+%
+% Basic approach:
+% to comment something out, scoop up  every line in verbatim mode
+% as macro argument, then throw it away.
+% For inclusions, in LaTeX the block is written out to
+% a file "comment.cut", which is then included.
+% In plain TeX (and other formats) both the opening and
+% closing commands are defined as noop.
+%
+% Trick for short in/exclude macros (\maybe{this snippet}):
+%\includeversion{cond}
+%\newcommand{\maybe}[1]{}
+%\begin{cond}
+%\renewcommand{\maybe}[1]{#1}
+%\end{cond}
+%
+% Changes in version 3.1
+% - updated author's address
+% - cleaned up some code
+% - trailing contents on \begin{env} line is always discarded
+%  even if you've done \includecomment{env}
+% - comments no longer define grouping!! you can even
+%   \includecomment{env}
+%   \begin{env}
+%   \begin{itemize}
+%   \end{env}
+%  Isn't that something ...
+% - included comments are written to file and input again.
+% Changes in 3.2
+% - \specialcomment brought up to date (thanks to Ivo Welch).
