The optional, keyword-only parameters argument_default_ and conflict_handler_
allow for finer-grained control of the behavior of the argument group. These
parameters have the same meaning as in the :class:`ArgumentParser` constructor,
but apply specifically to the argument group rather than the entire parser.

Note that any arguments not in your user-defined groups will end up back
in the usual "positional arguments" and "optional arguments" sections.
