+ * @short_description: event to control power level assignments
+ *
+ * This is the default event handler for `m.room.power_levels` events.
+ *
+ * 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 set in `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 the keys `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.
