% Listings mode
% =============
% The listings mode can be chosen by writing one of the following to the 
%listings-mode.tex file before compilation:
% \newcommand\listingsmode{default}   % to use lstlistings
% \newcommand\listingsmode{minted}    % for a script with exercises only
% The following lines include that file or make \listingsmode default to 
%'default' so that any derivatives of this project will work even without the 
%file.
\IfFileExists{listings-mode.tex}{
	\input{listings-mode.tex}
}{
	\newcommand\listingsmode{default}
}
