\section{Introduction}
This is a short example on how to use the bibstyler-Template. \\
Now we referer to the following literature:

\begin{itemize}
 \item{\bf Trends in Theoretical Computer Science \lit{boerger_trends83}}
 \item{\bf Science of Computer Programming \lit{SCP}}
 \item{\bf An Explanation of Splaying \lit{Subramanian:1994:ES}}
 \item{\bf Computer Science: The Nature of a Good and Accreditable Computer Science Program \lit{Martin96}}
\end{itemize}

And the same example with $\backslash$litsup:

\begin{itemize}
 \item{\bf Trends in Theoretical Computer Science \litsup{boerger_trends83}}
 \item{\bf Science of Computer Programming \litsup{SCP}}
 \item{\bf An Explanation of Splaying \litsup{Subramanian:1994:ES}}
 \item{\bf Computer Science: The Nature of a Good and Accreditable Computer Science Program \litsup{Martin96}}
\end{itemize}
