description: |-
  This event specifies the minimum level a user must have in order to perform a
  certain action. It also specifies the levels of each user in the room.

  If a ``user_id`` is in the ``users`` list, then that ``user_id`` has the
  associated power level. Otherwise they have the default level
  ``users_default``. If ``users_default`` is not supplied, it is assumed to be
  0.

  The level required to send a certain event is governed by ``events``,
  ``state_default`` and ``events_default``. If an event type is specified in
  ``events``, then the user must have at least the level specified in order to
  send that event. If the event type is not supplied, it defaults to
  ``events_default`` for Message Events and ``state_default`` for State
  Events. If there is no ``state_default`` in the ``power_levels`` event, the
  ``state_default`` is 50. If the room contains no ``power_levels`` event, the
  ``state_default`` is 0. The ``events_default`` is 0 in either of these cases.
