PARENT ROOMS

PARENT ROOMS

 Parent rooms are a subset of zones. If a room is used as a zone object,
 it is a parent room (PR). PRs are like local "master" rooms. Exits in
 the PR are global to that zone, and $commands on objects in the PR are
 global to that zone. Parent rooms are only defined if globals are used.
 Parent rooms should only be used for very large zones which have a lot
 of global exits. Otherwise, a ZMO thing should be used, because command
 evaluation on a parent room is slower than command evaluation on a ZMO.
 Large numbers of parent rooms may slow down the game significantly.
