\usage
\ctsimtext\ can be executed without any parameters. In that case, \ctsimtext\
-offers a command-line to enter the function-names and their parameters. The output of the command is displayed. Further commands may be given to \ctsimtext. The shell is exited by the {\tt quit} command.
+offers a command-line to enter the function-names and their parameters. The output of the command is displayed. Further commands may be given to \ctsimtext. The shell is exited by the \texttt{quit} command.
\ctsimtext\ can also be called to execute a single command. This is especially useful for batch files containing multiple \ctsimtext\ commands. This is invoked by calling \par
-{\tt ctsimtext function-name parameters...}.
