% \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.

% \subsection{Options}
%    \begin{macrocode}

% |texdepends| is easier to write with the |ifthen| package.
%    \begin{macrocode}
\RequirePackage{ifthen}

% \begin{option}{debug}
% The debug option (enable debug messages, useful for debuging)
%    \begin{macrocode}
\newboolean{TD@debug}

}%
%    \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.
