% \maketitle
%
% \begin{abstract}
%   The \theme{iis} theme for the \LaTeX{} \latexcls{beamer} class has
%   been developed at the Integrated Systems Laboratory (IIS). The
%   main purpose of the theme is to provide a minimalist layout with
%   regard to the space occupied by \emph{surrounding elements} such
%   as navigation bars, footer, or header and should basically work
%   out of the box at any workstation of the IIS IT
%   infrastructure. Thereby, most of the slide space can be filled
%   with actual content of the respective presentation.

% \section{Introduction}
% \todoin{Insert a small intro.}
%
% \section{Usage}
% \todoin{Describe the usage of the theme.}
%
% \section{Options}
% When loading the \theme{iis} theme, various options can be provided,
% which allow to adapt its behavior. In the following, the available
% options will be described.
%
%
% \subsection{List of Available Theme Options}
%
% \DescribeMacro{waferpng}
% Per default, the file type of the wafer image shown on the titlepage
% is a JPEG. Unfortunately, this file type does not allow any
% transparency in the shown picture. Therefore, there is a white
% border around the wafer image, which may cover parts of your text on
% the title slide (e.g., the authors or the affiliation). Thus, if
% needed, you can switch to the PNG version of the wafer image by
% providing the |waferpng| option. Note that by doing so the file size
% of the resulting PDF will increase, since the embedded PNG is larger
% than its JPG counterpart.
%
% \DescribeMacro{showheader}
% Usually, the available space for the content of the presentation
% should have utmost priority with regard to the layout of the
% slides. Therefore, we do not show any kind of navigation on the
% slides per default. If needed, a header can be shown by providing
% the |showheader| option of the theme, printing the section
% navigation on top of every slide.
%
% \DescribeMacro{hidefooter}
% If additional space is required on the slides, the footer can be
% hidden by providing the |hidefooter| option. Using this option while
% not providing the |showheader| option provides mainly a plain white
% slide layout and hence, the largest possible content space.
%
% \section{Commands}
% \todoin{Describe the provided commands.}
%
% \section{Caveats}
%
% \begin{itemize}
% \item The \theme{iis} \latexcls{beamer} theme has been designed to
%   work out of the box on the workstations of the Integrated Systems
%   Laboratory (IIS) using at least \texlive version
%   2011. Nevertheless, only minor adaptions should be necessary
%   (e.g., installing additional packages) to use it on any other
%   mature \TeX{} distribution.
% \end{itemize}
%
%
% \section{Known Bugs}
% \todoin{List the known bugs.}
%
% \section{Requested and Upcoming Features}
% \todoin{List the requested and upcoming features.}
%
% ^^A Indicate the start of the implementation part. This is important
% ^^A since the \CheckSum{} macro only counts the backslashes of the
% ^^A code (i.e., the lines not starting with a %) between the
% ^^A \StopEventually{} and the \Finale macro.
