keyword argument, which has the same interpretation as the

``action`` argument to ``argparse.ArgumentParser.add_argument()``,

with the addition of the special "nothing" action which completely
|

ignores the option (other than emitting the deprecation warning).

Note that the deprecation warning is only emitted once per

specific option string.
|
|
|
|
Note: If the ``real_action`` keyword argument specifies an unknown

action, no warning will be emitted unless the action is used, due

to limitations with the method used to resolve the action names.
