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.
67      \vspace{4mm}
68      \item<2-> The \texttt{mrun}-command has a number of options to control the
69      program execution\\
70         \quad \footnotesize \texttt{mrun -d example\underline{ }cbl -h lcsgih -K parallel -X8 -T2 ...}\\
71         \normalsize All options including a short description can be displayed by entering\\
72         \quad \footnotesize \texttt{mrun ?}
73      \vspace{4mm}
74      \item<3-> \normalsize The shellscript execution is also controlled by a configuration file with default name \texttt{.mrun.config}
