Perhaps this is OT, but since command line parsing is part of configuration, I figure I'd throw it out there. My scripts often have configuration that the command line can override and I loosely follow the example hierarchy[0] listed in The Art of Unix Programming. Some configuration I want in a config file (but I want to override from the command line) and sometimes it's very nice to use environment variables for configuration. So I do something like this: Integration with command line options is an occasionally-requested feature for ConfigObj. I've always said I would be open to patches... In other words, yes I think there is demand for it. Whether it belongs immediately in the standard library is another matter, but if you wrote a layer that unified ConfigParser and argparse I think you will find that people use it. It is well outside the realm of this PEP however. What Michael said. ;-) If you'd like to provide a patch for argparse that provides such functionality, I'd be happy to review it.

cfgparse appears to fill this role for optparse. It might be straightforward to port it to argparse.
