Currently, the application framework help text indicates for all tools in the help text: ``` The application can terminate with the following exit codes: 0 Application finished without errors. 1 Application finished after reporting an error to the end user. 2 Application crashed after running out of memory. 3 Application crashed for any reason other than running out of memory. ``` However, if in a ToolDef scrip a statement like `exit 5;` is executed, this determines the exit code instead. This should be indicated in the help text.
