distutils.fancy_getopt

Wrapper around the standard getopt module that provides the following
additional features:
  * short and long options are tied together
  * options have help strings, so fancy_getopt could potentially
    create a complete usage summary
  * options set attributes of a passed-in object

      * options have help strings, and help text can be assembled
        from them
      * options set attributes of a passed-in object
      * boolean options can have "negative aliases" -- eg. if
        --quiet is the "negative alias" of --verbose, then "--quiet"
        on the command line sets 'verbose' to false

SdS(	sParse command-line options in args. Store as attributes on object.

        If 'args' is None or not supplied, uses 'sys.argv[1:]'.  If
        'object' is None or not supplied, creates a new OptionDummy
        object, stores option values there, and returns a tuple (args,
        object).  If 'object' is supplied, it is modified in place and
        'getopt()' just returns 'args'; in both cases, the returned
        'args' is a modified copy of the passed-in 'args' list, which
        is left untouched.
