%
% Enable multiple versions of a document to be printed from one source file,
% especially if most of the text is shared between versions.
%
% Copyright 1993,1999,2001,2005 by Donald Arseneau (asnd@triumf.ca).
% This software is released under the terms of the LaTeX Project Public 
% License  (ftp://ctan.tug.org/tex-archive/macros/latex/base/lppl.txt).
% (Essentially: Free to use, copy, distribute (sell) and change, but, if
% changed, that fact must be made apparent to the user.)  It has a
% status of "maintained".
%
%
% HOW TO USE
% ~~~~~~~~~~
% One way to use this package is to declare (for example)
%
%     \usepackage[opta]{optional}
%
% at the beginning of your document, and flag optional text throughout 
% your document like:
%
%     \opt{opta}{Do this if option opta was declared}
%     \opt{optb}{Do this if option optb was declared}
%     \opt{optx,opty}{Do this if either option optx or opty}
%     \opt{}{Never print this text!}
%     \opt{opta}{\input{appendices}}
%     \optv{xam}{Type: \verb|[root /]$ rm -r *|.}
%
% Note that both the package option and the "\opt" argument can contain
% lists of options although, in practice, one or the other should be a
% single option name.  Lists are allowed in both places to allow more
% flexibility in the style of use. (But making the definitions much more
% difficult, Grrr.)
%
% Just as for "\includeonly", you will have to edit the main document
% file to switch option codes (i.e., change the "\usepackage" line).  
% There are, however, several ways to use this package without altering 
% the main document file: separate files, file-name sensing, interactive 
% prompting, and command-line option selection.
%
% Typically, different versions of a document will require different 
% document class and package setup, besides the different tags for
% optional.sty.  In that case it is best to have a separate main file
% for each version of the document.  Each stub file will declare the 
% document class and load some packages (including this one) and then 
% input the rest of the document from a file common to all versions.
%
%     \documentclass[A0]{poster}
%     \usepackage[poster]{optional}
%     \input{my_paper}
%
% If the different opt-tags match the different stub file names (file
% poster.tex will typeset the "poster" version) then you can specify
%
%     \usepackage[\jobname]{optional}
%
% Alternatively, this "\jobname" technique can make use of symbolic links, 
% if your computer system supports them, by having a single main input
% file accessed under different names (and different "\jobname"s).
%
% Another scheme is to invoke LaTeX with the command line such as:
%
%     latex "\def\UseOption{opta,optb}\input{file}"
%
% (with quoting appropriate to your operating system) then options "opta" 
% and "optb" will be used in addition to any options specified with the
% "\usepackage" command.
%
% You can prompt yourself to specify the option(s) with every run 
% through LaTeX:
%
%     \usepackage{optional}
%     \newcommand{\ExplainOptions}{man = users manual, check = checklist,
%           ref = reference card, post = poster.}
%     \AskOption
%
% The definition of "\ExplainOptions" is optional; it only serves to help
% the person who answers the question.  The "\AskOption" is also optional;
% it will be executed automatically whenever optional.sty sees no list of
% options.  This method is too tedious to use much.
%
% The normal restrictions forbidding special characters in package options
% and reference tags apply also the the tags used by the "\opt" command.
%
% These are not `comment' macros: The optional text must be well-formed
% with balanced braces, even if not printed.  The "\opt" command *IS* 
% completely `expandable' which means  it is robust and can even be used
% in messages ("\typeout").  
%
% As usual, "\verb" commands and verbatim environments cannot be used 
% in the argument to "\opt".  For this purpose there is a variant form
% of "\opt" called "\optv" (optional verbatim) which may have a limited
% class of verbatim material in the argument.  It can do so by leaving
% the braces around the argument, which may have undesired side effects.
% For an "\optv" argument to be successfully ignored, the verbatim material
% must have balanced braces etc.
%
% The "\opt" command is only intended for small sections of text.  If you
% need to optionally include whole sections or chapters, put that material
% in a separate file, and "\opt"-ionally use an "\input" command:
%
%     \opt{internal}{\input{prog_listings}}
