% \section{Purpose of these document classes}
% The following document classes were made by and for the HSR-Stud organization. 
% These classes are intended to be used to create beautiful summaries and cheat 
% sheets. Available classes are:
% \begin{description}[align=right]
%   \item[|hsrzf|] For summaries (Zusammenfassung)
%   \item[|hsrbericht|] For reports (Bericht)
% \end{description}
%
% 
% \section{Class Options}
% \begin{description}[align=right]
%   \item[\tt sans] Use Sans-Serif fonts (|cmbright| and |hfbright|).
%   \item[\tt slab] Use Slab-Serif fonts (|bitter| and |eulervm|).
%   \item[\tt margin=<size>] Sets up margins to reasonable size.

%   \toprule
%   Size & H & V & Size & H & V \\
%   \midrule
%   huge    & 45 & 40 & small   & 20 & 20 \\
%   large   & 35 & 35 & tiny    & 10 & 20 \\

% \caption{Sizes for the {\tt margin} option. All sizes are in millimeters}
% \end{table}
% 
% 
% \section{Extra Metadata}
% Thanks to the {\tt titling} package, normal metadata informations are available 
% throug the following commands: \cs{theauthor}, \cs{thedate}, \cs{thetitle}. 
% Additionally, more metadata variables have been created for this class, to 
% conserve informations related to the university course.
% \begin{description}[align=right]
%   \item[\cs{course}] The degree programme of the discussed subject.
%     Example: |Elektrotechnik|
%   \item[\cs{module}] Short name of the module according to the class 
%     schedule. Example: |ComEng1|
%   \item[\cs{semester}] Semester during which the summarized subject was 
%     taught. Example: |FS20|
%   \item[\cs{institute}] Internal institute in which the module was taught. 
%     This field is optional.
%   \item[\cs{authoremail}] Email of the author. This field is optional.
%   \item[\cs{maintainer}] Name of the person maintaining the work. This 
%     field is optional.
%   \item[\cs{contributors}] List of names of those who have contributed to
%     the document. This field is optional.
% \end{description}
% Like \cs{date}, \cs{title}, etc. these fields have too an accessor macro 
% \cs{the<metadata>}. For example: \cs{thecourse}, \cs{themodule}, and so on.
