ToolDef interpreter help text does not explain ToolDef script exit codes correctly

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.
