%
% A |beamer| outer theme dictates the style of the frame elements traditionally
% set outside the body of each slide: the head, footline, and frame title.

% \subsubsection{Package dependencies}
%
% \begin{macrocode}
\RequirePackage{etoolbox}

}
% \end{macrocode}
% \end{macro}
%
% \begin{macro}{progressbar}
% Adds a progress bar to the top, bottom, or frametitle of each slide.
% \begin{macrocode}

% \begin{macro}{headline}
% \begin{macro}{footline}
% Templates for the head- and footline at the top and bottom of each frame.

%
%
% \begin{macro}{appendix}
% Removes page numbering and per-slide progress bars when |\appendix| is

% |appendixnumberbeamer|.
