Yea I have had my eye on docopt for a while, it doesn't support multiple
subparsers, as I am passing duplicate parameters from its perspective.

Imagine:

foo.py --host 172.18.0.4 --port 766 foo --warning 42 --critical 77 bar --warning 4.2 --critical 7.7

etc...

The shortcoming to argparse has been debated to death and the bug tracker
was just left hanging. To be honest, I am not clear on the opposition to it...
