"description": "This event specifies the minimum level a user must have in order\nto perform a certain action. It also specifies the levels\nof each user in the room. If a ``user_id`` is in the\n``users`` list, then that ``user_id`` has the associated\npower level. Otherwise they have the default level\n``users_default``. If ``users_default`` is not supplied,\nit is assumed to be 0. The level required to send a\ncertain event is governed by ``events``, ``state_default``\nand ``events_default``. If an event type is specified in \n``events``, then the user must have at least the level\nspecified in order to send that event. If the event type is\nnot supplied, it defaults to ``events_default`` for Message\nEvents and ``state_default`` for State Events.",
