\begin{quote}
\color{red}\textbf{NOTE:} The \texttt{lstlisting} environment has been deliberately disabled in this setup.
Use \emph{inline code} (breakable and \emph{without} a caption) or create a \emph{float container} with 
\texttt{{\textbackslash}begin\{program\} \ldots {\textbackslash}end\{program\}} instead!
See the \texttt{hgbthesis} tutorial for examples.
