% \section{Introduction}
% This package automatically generates dependancies on \LaTeX\ files and
% packages, figures, bibliography files, glossary and index files. The
% generated file is then used by a Makefile to handle dependancies.
% \StopEventually{

% \section{Implementation of texdepends}
% \subsection{Options}
%    \begin{macrocode}
%<*package>
%    \end{macrocode}
% |texdepends| is easier to write with the |ifthen| package.
%    \begin{macrocode}
\RequirePackage{ifthen}
%    \end{macrocode}
% \begin{option}{debug}
% The debug option (enable debug messages, useful for debuging)
%    \begin{macrocode}
\newboolean{TD@debug}
\newcommand{\TD@option@debug}[1][true]{%
  %\PackageWarningNoLine{texdepends}{Setting debug to #1}
  \setboolean{TD@debug}{#1}%
}%
%    \end{macrocode}
% \end{option}
% \begin{option}{extension}
% The extension option. We can use it to let |texdepends|
% know whether we compile a dvi or a pdf file.
%    \begin{macrocode}
\def\TD@option@extension[#1]{%
  %\PackageWarningNoLine{texdepends}{Using extention #1}
  \def\TD@extention{#1}%
}%
%    \end{macrocode}
% \end{option}
% Managing options with specific code. Using the |keyval|
% package could be a solution, but this would add one more dependency.
%    \begin{macrocode}
\def\TD@option@split#1=#2=#3\relax{%
  \def\TD@option@name{#1}%
  \ifx\TD@option@name\@empty\else

    \else
      \ifx\@empty#3\@empty
         \TD@option@cmd\relax%
      \else
        \def\TD@option@value{#2}%
        \TD@option@cmd[\TD@option@value]%
      \fi
    \fi
  \fi
}%
%    \end{macrocode}
% All option are managed by the same code.

\DeclareOption*{%
  %\PackageWarningNoLine{texdepends}{Option \CurrentOption}%
  \expandafter\TD@option@split\CurrentOption==\relax%

%    \end{macrocode}
% So lets process options
%    \begin{macrocode}
\ProcessOptions
%    \end{macrocode}
% If the |extension| option is not used, we try to find ourselves
% the good extension based on TeX engine or mode.
