Hi,

	I am using a fine LaTeX style file which I think can be
	exteremly useful for anyone writing Journal and Conference
	versions of the same paper. This file is enclosed below.
	As a programmer, I believe the services provided by this
	macro package are so elementary they should have been
	supplied with TeX. However, Don thinks otherwise. 

	There are some problems: a) \begin{Someting} ... \end{Something}
	when it is exluded would not work in the \title command of LaTeX.
	instead error messages are produced.
	b) changing the page dimension inside an environment has no
	effect.

   I tried reading the source, but even after a lot of wading through
   the TeX book, it still looks like ancient sansscript (...)  to me.

	The file has only the name but not the address of the author.

	Can you help in locating, or in solving the problem?

% Version control macros. These let you define environments whose contents
% will be optionally added to or deleted from the text when you run LaTeX.
% Usage: place either of the following near the start of your file:
%     \includeversion{NAME}
%     \excludeversion{NAME}
% Here, "NAME" is any name you choose. The first one indicates that text
% between \begin{NAME} and \end{NAME} will be processed in the normal way.
% The second indicates that text between \begin{NAME} and \end{NAME} will
% be totally deleted.
% You can define environments for as many versions as you want. 
% A ``comment'' environment has already been pre-defined for you with 
% \excludeversion{comment}; you can override this using \includeversion.
%
% Example: 
%   \includeversion{abridged}\excludeversion{unabridged}
%   Text for the
%   \begin{abridged} 
%      short
%   \end{abridged}
%   \begin{unabridged}
%      long and really longwinded, opaque and boring
%   \end{unabridged}
%   version of the paper. Punctuation works correctly\begin{unabridged}
%   because sphack is used\end{unabridged}.
%   \begin{comment} This is deleted by default. \end{comment}
