-Converting the namespace to a dict
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

-It's possible to convert a namespace to a :class:`dict` by using the built-in
-function :func:`vars` in this fashion::
-
- args = parser.parse_args()
- argdict = vars(args)
-
-This makes it easy to introspect the namespace or to pass the command-line
-arguments to a function taking a bunch of keyword arguments::
-
- somefunction(**vars(parser.parse_args()))
