Hi, thanks for sharing great project!
When I was using your lib i noticed this bug:
ArgumentParser object requires keyword argument
descriptioninstead ofhelpaccording to https://docs.python.org/3/library/argparse.html#argparse.ArgumentParserNow after this fix, when you type
<command_name> -halso docstring from command class is printed.Later I also noticed that, when i replaced
helpkwarg withdescriptionkwarg the<app_name> --helpbroke. There wasn't info about commands.So, finally instead of replacing arguments I added
descriptionkwarg and now the docstring is visible in both: app help and command help
