     1.5 -% Comment.sty   version 3.6, October 1999
     1.6 -%
     1.7 -% Purpose:
     1.8 -% selectively in/exclude pieces of text: the user can define new
     1.9 -% comment versions, and each is controlled separately.
    1.10 -% Special comments can be defined where the user specifies the
    1.11 -% action that is to be taken with each comment line.

    1.39 -%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
    1.40 -% This style can be used with plain TeX or LaTeX, and probably
    1.41 -% most other packages too.
    1.42 -%
    1.43 -% Usage: all text included between
    1.44 -%    \comment ... \endcomment
    1.45 -% or \begin{comment} ... \end{comment}
    1.46 -% is discarded. 
    1.47 -%
    1.48 -% The opening and closing commands should appear on a line
    1.49 -% of their own. No starting spaces, nothing after it.
    1.50 -% This environment should work with arbitrary amounts
    1.51 -% of comment, and the comment can be arbitrary text.
    1.52 -%
    1.53 -% Other `comment' environments are defined by
    1.54 -% and are selected/deselected with
    1.55 -% \includecomment{versiona}
    1.56 -% \excludecoment{versionb}
    1.57 -%
    1.58 -% These environments are used as
    1.59 -% \versiona ... \endversiona
    1.60 -% or \begin{versiona} ... \end{versiona}
    1.61 -% with the opening and closing commands again on a line of 
    1.62 -% their own.
    1.63 -%
    1.64 -% LaTeX users note: for an included comment, the
    1.65 -% \begin and \end lines act as if they don't exist.
    1.66 -% In particular, they don't imply grouping, so assignments 
    1.67 -% &c are not local.
    1.68 -%
    1.69 -% Special comments are defined as
    1.70 -% \specialcomment{name}{before commands}{after commands}
    1.71 -% where the second and third arguments are executed before
    1.72 -% and after each comment block. You can use this for global
    1.73 -% formatting commands.
    1.74 -% To keep definitions &c local, you can include \begingroup
    1.75 -% in the `before commands' and \endgroup in the `after commands'.
    1.76 -% ex:
    1.77 -% \specialcomment{smalltt}
    1.78 -%     {\begingroup\ttfamily\footnotesize}{\endgroup}
    1.79 -% You do *not* have to do an additional
    1.80 -% \includecomment{smalltt}
    1.81 -% To remove 'smalltt' blocks, give \excludecomment{smalltt}
    1.82 -% after the definition.
    1.83 -%
    1.84 -% Processing comments can apply processing to each line.
    1.85 -% \processcomment{name}{each-line commands}%
    1.86 -%    {before commands}{after commands}
    1.87 -% By defining a control sequence 
    1.88 -% \def\Thiscomment##1{...} in the before commands the user can
    1.89 -% specify what is to be done with each comment line.
    1.90 -% BUG this does not work quite yet BUG
    1.91 -%
    1.92 -% Trick for short in/exclude macros (such as \maybe{this snippet}):
    1.93 -%\includecomment{cond}
    1.94 -%\newcommand{\maybe}[1]{}
    1.95 -%\begin{cond}
    1.96 -%\renewcommand{\maybe}[1]{#1}
    1.97 -%\end{cond}
    1.98 -%
    1.99 -% Basic approach of the implementation:
   1.100 -% to comment something out, scoop up  every line in verbatim mode
   1.101 -% as macro argument, then throw it away.
   1.102 -% For inclusions, in LaTeX the block is written out to
   1.103 -% a file \CommentCutFile (default "comment.cut"), which is
   1.104 -% then included.
   1.105 -% In plain TeX (and other formats) both the opening and
   1.106 -% closing comands are defined as noop.
   1.107 -%
   1.108 -%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
   1.109 -% Changes in version 3.1
   1.110 -% - updated author's address
   1.111 -% - cleaned up some code
   1.112 -% - trailing contents on \begin{env} line is always discarded
   1.113 -%  even if you've done \includecomment{env}
   1.114 -% - comments no longer define grouping!! you can even
   1.115 -%   \includecomment{env}
   1.116 -%   \begin{env}
   1.117 -%   \begin{itemize}
   1.118 -%   \end{env}
   1.119 -%  Isn't that something ...
   1.120 -% - included comments are written to file and input again.
   1.121 -% Changes in 3.2

   1.126 -% Changes in 3.4
   1.127 -% - added GNU public license

   1.134 -% - fixed excludecomment of an earlier defined environment.
   1.135 -% Changes in 3.6
   1.136 -% - The 'cut' file is now written more verbatim, using \meaning;
   1.137 -%   some people reported having trouble with ISO latin 1, or umlaute.sty.
   1.138 -% - removed some \newif statements.
   1.139 -%   Has this suddenly become \outer again?
   1.140 -%
   1.141 -% Known bugs:
   1.142 -% - excludecomment leads to one superfluous space
   1.143 -% - processcomment leads to a superfluous line break
