%\section{Introduction}
%\label{sec:intro}
%
% Deutsches museum regularly publishes studies.  This package provides
% the way to the authors to format the contributions in \LaTeX.  
%
%
%\section{Options}
%\label{sec:ug_options}
%
% \DescribeOptions{cfonts,nocfonts}%
% The contributions to Deutsches Museum should use their fonts:
% Garamond Berthold BQ and Futura PT.  You probably want to buy them
% and install.  If you do not have them, use the options |nocfonts| to
% substitute them for free fonts available in standard \TeX\
% distriutions.  The option |cfonts| (the default) uses commercial
% fonts.
%
% In both cases the package uses fonts in OTF formats, so you need to
% use Lua\TeX\ or Xe\TeX\ for the compilation.
%
% If you use commercial fonts, the package expects the file names
% listed in Table~\ref{tab:fonts}.
%
% \begin{table}
%   \centering
%   \begin{tabularx}{\textwidth}{>{\raggedright}Xl}
%       \toprule
%       Font & File\\
%       \midrule
%       Garamond BQ Regular & |GaramondBQ-Regular.otf|\\
%       Garamond BQ Italic & |GaramondBQ-Italic.otf| \\
%       Garamond BQ Bold & |GaramondBQ-Bold.otf|\\
%       Garamond BQ Medium Italic & |GaramondBQ-MediumItalic.otf|\\
%       Futura PT Light & |futura-pt_light.otf|\\
%       Futura PT Light Oblique & |futura-pt_light-oblique.otf|\\
%       Futura PT Medium & |futura-pt_medium.otf|\\
%       Futura PT Medium Oblique & |futura-pt_medium-oblique.otf|\\
%       Futura PT Condensed Medium & |futura-pt_cond-medium.otf|\\
%       Futura PT Condensed Medium Oblique & |futura-pt_cond-medium-oblique.otf|\\
%       \bottomrule
%     \end{tabularx}
%   \caption{Commerical fonts (if the option \texttt{cfonts} is used)}
%   \label{tab:fonts}
% \end{table}
%
% \DescribeOption{garamondmath,nogaramondmath}%
% By default the class uses \textsl{unicode-math} with Garamond math
% package.  The option |nogaramondmath| disables this behavior, so you
% can experiment with other math styles.
%
% Internally the class uses \textsl{amsart}, so all its options are
% supported.  
%
% \DescribeOption{folios,nofolios}%
% Deutsches Museum prefers to put running titles and page numbers in
% the post production, 
% so we omit them by default.  The option |folios| restores them,
% while the option |nofolios| (default) suppresses them.
%
%
%\section{Floats}
%\label{sec:ug_floats}
%
% We put captions \emph{before} tables and \emph{after} figures.
%
%\section{Front matter}
%\label{sec:ug_frontmatter}
%
% \DescribeMacro{\title}%
% As in \textsl{amsart} package, the \cs{title} command has an
% optional argument, that defines \cs{shortitle} macro, used for
% running heads.
%
% \DescribeMacro{\subtitle}%
% Deutsches Museum contributions, along with the title, have
% |\subtitle|.  The running heads pick either short title, or
% subtitle, whichever is defined last.  You can override this choice
% by redefining |\shortitle|.  Examples
%
% \DescribeMacro{abstract}%
% Abstract, if present, should follow \cs{maketitle}
%
%\section{Bibliography}
%\label{sec:ug_biblio}
%
% The package uses bibliography in footnotes and |natbib| for
% formatting the bibliography list.  The command \cs{cite} produces
% footnote citations.

%\section{Implementation}
%\label{sec:impl}
%
%\subsection{Identification}
%\label{sec:ident}
%
% We start with the declaration who we are.  Most |.dtx| files put
% driver code in a separate driver file |.drv|.  We roll this code into the
% main file, and use the pseudo-guard |<gobble>| for it.
%    \begin{macrocode}
