quit
The quit command can be used to exit PyXPlot. If multiple command files, or a mixture of command files and interactive sessions, are specified on the command line, then PyXPlot moves onto the next command-line item after receiving the exit command.
PyXPlot may also be quit be pressing CTRL-D or via the exit command. In interactive mode, CTRL-C terminates the current command, if one is running. When running a script, CTRL-C terminates execution of it.
