Camelot overrides click.HelpFormatter.write_usage

[dimitern]

Hey @vinayak-mehta, and thank you for making Camelot and Excalibur!

While working on adding tests for Excalibur (camelot-dev/excalibur#49), I've noticed this code:

def _write_usage(self, prog, args='', prefix='Usage: '):
    return self._write_usage('camelot', args, prefix=prefix)


# monkey patch click.HelpFormatter
HelpFormatter._write_usage = HelpFormatter.write_usage
HelpFormatter.write_usage = _write_usage

This monkey patching causes Excalibur's (or any other click-based) CLI to return camelot for the program name in the help output, which is a bit confusing, so I decided to add this issue and propose a PR to fix it.

Thanks for raising this issue and the corresponding PR! I didn't know about the name kwarg in click.group at the time and resorted to this monkey patch. Please give me some time to review and merge your PR.

Closing in favour of camelot-dev/camelot#5
