"""DEPRECATED - A manager to handle when cursors are killed after they are
closed.
New cursor managers should be defined as subclasses of CursorManager and can be
installed on a client by calling
:meth:`~pymongo.mongo_client.MongoClient.set_cursor_manager`.
.. versionchanged:: 3.3
Deprecated, for real this time.
.. versionchanged:: 3.0
Undeprecated. :meth:`~pymongo.cursor_manager.CursorManager.close` now
requires an `address` argument. The ``BatchCursorManager`` class is removed.
