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

Z d d d Z RS( sÕ Wrapper around the standard 'getopt()' module that provides some
handy extra functionality:
* short and long options are tied together
* 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

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.
