\ProvidesPackage{gmeometric}
     [2008/11/22 v0.73 to allow the `geometry' macro in the document (GM)]

%
%% \division{Introduction, usage}
%%
%% This package allows you to use the |\geometry| macro, provided by
%% the \pk{geometry} v3.2 and v4.1 by Hideo Umeki, anywhere in a~document:
%% originally it's claused |\@onlypreamble| and the main work of
%% \pk{gmeometric} is to change that.
%%
%% Note it's rather queer to change the page layout \emph{inside}
%% a~document and it should be considered as drugs or alcohol: it's
%% O.K.\ only if you \emph{really} know what you're doing.
%%
%% In order to work properly, the macro should launch the |\clearpage|
%% or the \cs{cleardoublepage} to `commit' the changes. So, the
%% unstarred version trigges the first while the starred the
%% latter. If that doesn't work quite as expected, try to precede or
%% succede it with |\onecolumn| or |\twocolumn|.
%%
%% It's important that |\clear(double)page| launched by |\geometry|
%% not to be a~no-op, i.e., |\clear(double)page| immediately
%% preceding |\geometry| (nothing is printed in between) discards the
%% `commitment'.
%%
%% \stanza
%% You may use \pk{gmeometric} just like \pk{geometry} i.e., to specify
%% the layout as the package options: they shall be passed to
%% \pk{geometry}.
%%
%% This package also checks if the engine is \XeTeX\ and sets the
%% proper driver if so. Probably it's redundant since decent \XeTeX\
%% packages provide their \pk{geometry.cfg} file that does that.
%%
%
% \begin{gmlonely}
%   \subdivision{Installation}
%   
%   Unpack the \file{gmeometric.tds.zip} archive in a~\file{texmf}
%   directory or put the \pk{gmeometric.sty} somewhere in the
%   \file{texmf/tex/latex} branch on your own. Creating
%   a~\file{texmf/tex/latex/gm} directory may be advisable if
%   you consider using other packages written by me.
%
%   Then you should refresh your \TeX\ distribution's files' database
%   most probably. 
% \end{gmlonely}
%
%
% \subdivision{Contents of the \pk{gmeometric.zip} archive}
%
% The distribution of the \pk{gmeometric} package consists of the
% following four files.
% \begin{verse}
%   \pk{gmeometric.sty}\\
%   \pk{README}\\
%   \pk{gmeometric.pdf}\\
%   \pk{gmeometric.tds.zip}
% \end{verse}
%
%
% \begin{gmlonely}
%   \subdivision{Compiling of the documentation}
%
%   The last of the above files (the \pk{.pdf}, i.e., \emph{this
%     file}) is a~documentation compiled from the \pk{.sty} file by
%   running \LaTeX\ (twice) on the \pk{gmeometric.sty} file 
%   (|xelatex gmeometric.sty|  in the directory you wish the
%   documentation to be in, you don't have copy the \file{.sty} file
%   there, \TeX\ will find it).
%   Compiling of the documentation requires the packages: \pk{gmdoc}
%   (\pk{gmdoc.sty} and \pk{gmdocc.cls}), \pk{gmverb.sty},
%   \pk{gmutils.sty}, \pk{gmiflink.sty} and also some standard
%   packages: \pk{hyperref.sty}, \pk{color.sty}, \pk{geometry.sty},
%   \pk{multicol.sty}, \pk{lmodern.sty}, \pk{fontenc.sty} that should
%   be installed on your computer by default.
%
%   If you have not installed the \pk{mwart.cls} class (available on
%   CTAN in \pk{mwcls} package), the result of your compilation may
%   differ a bit from the \pk{.pdf} provided in this \pk{.zip} archive
%   in formattings: If you have not installed \pk{mwart.cls}, the
%   standard \pk{article.cls} class will be used.
% \end{gmlonely}
%
%
% \division{Usage} The main use of this package is to allow the
% |\geometry| command also inside the \env{document} (originally it's
% |\@onlypreamble|). To make |\geometry| work properly is quite
% a~different business. It may be advisable to `commit' the layout
% changes with |\newpage|, |\clearpage|, or |\cleardoublepage| and
% maybe |\one/twocolumn|. 
%
% Some layout commands should be put before |\one/twocolumn| and other
% after it. An example:
%
%\begin{verbatim}
% \thispagestyle{empty}
%
% \advance\textheight 3.4cm\relax
% \onecolumn
% \newpage
%
% \advance\footskip-1.7cm
% \geometry{hmargin=1.2cm,vmargin=1cm}
% \clearpage
%\end{verbatim}
%
% And another:
%\begin{verbatim}
% \newpage
% \geometry{bottom=3.6cm}
%\end{verbatim}
%
% In some cases it doesn't work perfectly
% anyway. Well, the \acro{(LPPL)} license warns about it.
% 
% \division{The code}

\RequirePackage{gmutils}[2008/11/21]% this package defines the storing and
% restoring commands.

% Redefine |\@onlypreamble|, add storing to BeginDocument.
\newcommand*\gme@tobestored{{% this list consists of the \CS'es
    % relaxed at begin document by \pk{geometry} (the only
    % \incs{AtBeginDocument} in \pk{geometry} v4.1).
    % \changes{v0.73}{2008/11/22}{ two \CS'es added to the
    %   list for compatibility with \pk{geometry} v4.1}

\AtBeginDocument{\@xa\StoreMacros\gme@tobestored}
% \changes[\AtBeginDocument]{v0.73}{2008/11/22}{removed two
%   \cs{expandafter}s expanding \cs{gme@tobestored}: much less tokens
%   added to the begin-document hook}

% To make it work properly in \XeTeX:

}{}

\RequirePackageWithOptions{geometry}

% Restore |\@onlypreamble|:

% Hypothesis: |\ifx...\@undefined| fails in the document because
% something made |\csname Gm@lines\endcsname|. So we change the test
% to decent. And i~think I've found the guilty: |\@ifundefined| in
% |\Gm@showparams|. So I~change it to the more elegant
% |\ifx\@undefined|.
