I'm not sure what you mean -- I thought they added a funclect, not a

I think on_stop should conform more to these params:
after_each_exec
before_any_exec
after_all_exec
E.g.,
before_mtt_start_exec
after_mtt_start_exec
Then have &_process_get_value_option() call DoCommand. Note, DoCommand
is aware of hashbangs (see &_contains_shell_script_characters()), so
&shell_script() might be redundant.
