+What's New (2020-01-01) Replace use of \count0 with new counter \eqtmpcnta, 
+in situation, the value of \count0 was leaking out giving incorrect page 
+numbers.

 What's New (2019-12-17) Defined \InputExrSolnsLevel and \InputQzSolnsLevel to
 make it easy to change the section-type for the solution pages.

+% Purpose:
 % 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.

+%% Guide to special effects
+%%
+% To understand what happens here, you need to know just a bit about
+% the implementation. Lines inside a comment are scooped up one at a
+% time, and written to an external file. This file can then be
+% included, or ignored. Or you can do stuff with it as you'll see now.
 %
 % 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.
+% and after each comment block. You can use this for global
+% formatting commands.
 % To keep definitions &c local, you can include \begingroup
 % in the `before commands' and \endgroup in the `after commands'.
+% ex:
+% \specialcomment{smalltt}
+%     {\begingroup\ttfamily\footnotesize}{\endgroup}
+% Of course, in this case you could probably have used the standard
+% LaTeX \newenvironment.
+%
+% With \specialcomment you do *not* have to do an additional
+% \includecomment{smalltt}
+% To remove 'smalltt' blocks, give \excludecomment{smalltt}
+% after the definition.
+%
+% The comment environments use two auxiliary commands. You can get
+% nifty special effects by redefining them.
+% 1/ the commented text is written to an external file. Default definition:
+%   \def\CommentCutFile{comment.cut}
+% 2/ included comments are processed like this:
+%   \def\ProcessCutFile{\input{\CommentCutFile}\relax}
+% and excluded files have
+%   \def\ProcessCutFile{}
 %
-% 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.
+% Fun use of special comments: the inclusion of the comment is done
+% by \ProcessCutFile, so you can redefine that:
+% \specialcomment{mathexamplewithcode}
+%  {\begingroup\def\ProcessCutFile{}} %1
+%  {\verbatiminput{\CommentCutFile}   %2
+%   \endgroup
+%   This gives:
+%   \begin{equation} \input{\CommentCutFile} \end{equation}
+%  }
+% 1: do not standard include the file
+% 2: input it verbatim, then again inside display math
 %
-% Trick for short in/exclude macros (\maybe{this snippet}):
-%\includeversion{cond}
+% You can also apply processing to each line.
+% By defining a control sequence
+% \def\Thiscomment##1{...} in the before commands the user can
+% specify what is to be done with each comment line. If something
+% needs to be written to file, use \WriteCommentLine{the stuff}
+% Example:
+% \specialcomment{underlinecomment}
+%  {\def\ThisComment##1{\WriteCommentLine{\underline{##1}\par}}
+%   \par}
+%  {\par}
+%
+% Trick for short in/exclude macros (such as \maybe{this snippet}):
+%\includecomment{cond}
 %\newcommand{\maybe}[1]{}
 %\begin{cond}
 %\renewcommand{\maybe}[1]{#1}
 %\end{cond}
