I don't understand why I shouldn't be using argparse. Just using argparse means no mess of 'getopt vs optparse vs argparse' because I am not using all those other libraries. I don't see anything seriously wrong for argparse. How does it help me to use a third party module rather than argparse?
Using argparse is probably the safest approach. However, argparse does not work with config files; groper does. So if you have more than a half-dozen options, you should use groper (or something similar).
