Keeping getopt around and including a "addgetoptarguments" method in argparse is probably the best of both worlds, in that it allows for relatively straightforward evolution of an application:

1. Start with getopt 2. As the getopt argument parsing gets twisty and arcane and maintaining the help string becomes a nightmare, move to argparse with the "addgetoptarguments" method. 3. Over time, convert more arguments to proper argparse arguments with full documentation.

Maybe. I haven't been following this entire thread, but I don't see
much point in making it easy to go from getopt to argparse. The two
are so different that I think you're either going to jump all in or
not. Maybe that's just me though as I really don't see much use for
getopt any more (even for throwaway scripts).
