 \subsection{Execution}
 
 To execute the optimizer, the following command can be given:\\
-\texttt{./main <original file> <optimized file> <rewritten original file>}
+\texttt{./main.py <original file> <optimized file> <rewritten original file>}\\
+There is also a script available that runs the optimizer and automatically
+starts the program \emph{meld}. In meld it is easy to visually compare the
+original file and the optimized file. The command to execute this script is:\\
+\texttt{./run <benchmark name (e.g. whet)>}\\
