An exit links one location to another location, providing a way to travel on the MUX. Although normally used to link rooms together, exits can be made to and from players and objects.
You may pick up exits that you own, and drop exits into locations that you own. When you pick up or drop an exit, anyone in the exit's new location may use the exit and travel to its destination. Exits may also be @teleported from one room to another.
If an exit is set DARK it will not show up in the list of obvious exits in a room.
If multiple exits match in name, MUX chooses between them randomly.
Another way of creating 'variable' exits is to use the @exitto attribute.
