RULES

NAME
        room - rules on rooms


DESCRIPTION
	All rooms that can be accessed by players must also be accessible for
	the admin. If they are not, they will be adjusted to that purpose

	GUIDE LINES

	The room object is the most common object in the game! In order to
	make it possible to save memory, it is strongly recommended that you
	use the standard rooms, /std/*room.c, as a base for your area.

	Things should be possible to look at in your rooms. If you use the
	standard room object, this is very easy to accomplish. Also mark the
	room as indoors or outdoors. Look in the code of the example rooms
	under /examples on how to do this.
