63   \begin{itemize}
64      \item<1-> \texttt{mrun} (\textbf{m}odel \textbf{run}) is a shell script (using
65      \texttt{ksh}-syntax) which can be used to compile and run programs, including
66      the handling of input/output files.
[954]67      \vspace{4mm}
[945]68      \item<2-> The \texttt{mrun}-command has a number of options to control the
69      program execution\\
[954]70         \quad \footnotesize \texttt{mrun -d example\underline{ }cbl -h lcsgih -K parallel -X8 -T2 ...}\\
[945]71         \normalsize All options including a short description can be displayed by entering\\

[954]73      \vspace{4mm}
[945]74      \item<3-> \normalsize The shellscript execution is also controlled by a configuration file with default name \texttt{.mrun.config}
