            [2007/03/02 v0.75 a class for gmdoc driver files (GM)]

%
% \division{Intro}
%%
%% This file is a~part of \pk{gmdoc} bundle and provides a~document
%% class for the driver files documenting \LaTeXpar\ packages \&a.\
%% with my \pk{gmdoc.sty} package. It's not necessary, of course: most
%% probably you may use another document class you like.
%%
%% By default this class loads \pk{mwart} class with a4paper (default)
%% option and \pk{lmodern} package with QX fontencoding. It loads also
%% my \pk{gmdoc} documenting package which loads some auxiliary
%% packages of mine and the standard ones.
%% 
%% If the \pk{mwart} class is not found, the standard \pk{article}
%% class is loaded instead. Similarly, if the \pk{lmodern} is not
%% found, the standard Computer Modern font family is used in the
%% default font encoding.
%% 
%
% \division{Usage}
%
% For the ideas and details of \pk{gmdoc}ing of the \LaTeXpar\ files
% see the \pk{gmdoc.sty} file's documentation (chapter \ref{gmd}). The
% r\^ole of the \pk{gmdocc} document class is rather auxiliary and
% exemplary.  Most probably, you may use your favourite document class
% with the settings you wish. This class I~wrote to meet my needs of
% fine formatting, such as not numbered sections and sans serif demi
% bold headings.
%
% However, with the users other than myself in mind, I~added some
% conditional clauses that make this class works also if an \pk{mwcls}
% class or the \pk{lmodern} package are unknown.  \dekmedskip
%
% Of rather many options supported by \pk{gmdoc.sty}, this class
% chooses my favourite, i.e., the default. An exception is made for
% the \TextUsage*{noindex} option, which is provided by this class and
% passed to \pk{gmdoc.sty}. This is intended for the case you don't
% want to make an index.
%
% Simili modo, the \TextUsage*{nochanges} option is provided to turn
% creating the change history off. 
%
% Both of the above options turn the \emph{writing out to the files}
% off. They don't turn off |\PrintIndex| nor |\PrintChanges|. (Those
% two commands are no-ops by themselves if there's no \file{.ind}
% (n)or \file{.gls} file respectively.)
% \dekmedskip
%
% One more option is \TextUsage*{outeroff}. It's intended for
% compiling the documentation of macros defined with the |\outer|
% prefix. It |\relax|es this prefix so the `|\outer|' macros' names can
% appear in the arguments of other macros, which is necessary to
% pretty mark and index them. 
%
% I~decided not to make discarding |\outer| the default because
% it seems that \LaTeX\ writers don't use it in general and
% \pk{gmdoc.sty} \emph{does} make some use of it.
% \dekmedskip
% 
% This class provides also the \TextUsage*{debug} option. It turns the
% |\if@debug| Boolean switch True and loads the \pk{trace} package that
% was a~great help to me while debugging \pk{gmdoc.sty}.
% \dekmedskip
%
% The default base document class loaded by \pk{gmdocc.cls} is Marcin
% Woli\'nski's \pk{mwart}. If you have not installed it on your
% computer, the standard \pk{article} will be used. 
%
% Moreover, if you like MW's classes (as I~do) and need |\chapter|
% (for multiple files' input e.g.), you may declare another \pk{mwcls}
% with the option homonimic with the class'es name: \TextUsage*{mwrep}
% for \pk{mwrep} and \TextUsage*{mwbk} for \pk{mwbk}. For the symmetry
% there's also \TextUsage*{mwart} option (equivalent to the default
% setting).
%
% The existence test is done for any MW class option as it is in the
% default case.
%
% \stanza
% The \TextUsage\EOFMark\ is in this class typesets like this (of
% course, you can redefine it as you wish):\par\EOFMark

% \division{The Code}

% \CodeDefIndex\gmcc@baseclass
\def\gmcc@baseclass{mwart}% the default is Marcin Woli\'nski's class (\pk{mwcls})
% analogous to \pk{article}.

% Since you can choose the standard \pk{article} class, we'd better
% provide a~Boolean switch to keep the score of what was chosen. It's
% to avoid unused options if \pk{article} is chosen.
%\CodeDefIndex*{gmcc@mwcls}
\newif\ifgmcc@mwcls
\gmcc@mwclstrue
% \CodeDefine*{mwart}
\DeclareOption{mwart}{\def\gmcc@baseclass{mwart}}% The \pk{mwart} class may also
% be declared explicitly.
% \CodeDefine*{mwrep}
\DeclareOption{mwrep}{\def\gmcc@baseclass{mwrep}}% If you need
% chapters, this option chooses an MW's class that corresponds to
% \pk{report},
% \CodeDefine*{mwbk}
\DeclareOption{mwbk}{\def\gmcc@baseclass{mwbk}}% and this MW's class
% corresponds to \pk{book}.
% \CodeDefine*{article}
\DeclareOption{article}{\gmcc@mwclsfalse}% you can also
% \emph{choose} \pk{article}.


% \CodeDefine*{outeroff}
\DeclareOption{outeroff}{\let\outer\relax}% This option allows
% |\outer|-prefixed macros to be \pk{gmdoc}-processed with all the
% bells and whistles.

% \CodeDefine\if@debug
\newif\if@debug
% \CodeDefine*{debug}
\DeclareOption{debug}{\@debugtrue}% This option causes \pk{trace} to
% be loaded and the Boolean switch of this option may be used to hide
% some things needed only while debugging.

% \CodeDefine*{noindex}
\DeclareOption{noindex}{%
  \PassOptionsToPackage{\CurrentOption}{gmdoc}}% This
% option turns the writing outto \file{.idx} file off.

% \CodeDefIndex\if@gmccnochanges
% \CodeDefIndex*\@gmccnochangestrue
% \CodeDefIndex*\@gmccnochangesfalse
\newif\if@gmccnochanges
% \CodeDefine*{nochanges}
\DeclareOption{nochanges}{\@gmccnochangestrue}% This option turns the
% writing outto \file{.glo} file off.

% \CodeDefine*{gmeometric}
\def\gmTheGeometry{geometry}
\DeclareOption{gmeometric}{%
  \IfFileExists{gmeometric.sty}{%
    \def\gmTheGeometry{gmeometric}}{}}% It's an experimental option
% that causes the |\geometry| macro provided by \pk{geometry} package
% is not restricted to the preamble. This option causes the
% \pk{gmeometric} package is loaded (if available) that works the
% limitation around.
