% \section{Introduction}
%
% \subsection{General}
% \DescribeMacro{\includegraphics}
% This package allows to load XFig figures from \LaTeX\space sources with
% the |\includegraphics| command from the |graphicx| package:
% \begin{verbatim}
% \includegraphics[width=\linewidth]{myfig.fig}
% \end{verbatim}
%
% This package does not convert by itself XFig figures (see package
% |texdepends| for that). It only diverts the loading functions so
% that \LaTeX\space includes the |.pstex_t| or the |.pdftex_t|.
%
% \subsection{Options}
% Available options for this package:
% \begin{description}
% \item[debug~:] \DescribeOption{debug}more messages written while compiling
% \end{description}
%
% \DescribeFile{figlatex.cfg}
% \DescribeMacro{\debug}
% When the package is loaded, it tries to read a |figlatex.cfg|
% file. This file can contains |\debug| to
% enable this option site wide.
%
% \subsection{Subfigures}
%
% Sometimes, several figures made with XFig should be similar. It is
% possible to make only one XFig figure and then create subfigures
% which contains only a subset of the depths of the original figure.
