| 8 | * Exits of the room (obvious ones, doors, and special ones) |
| 9 | * we define the following function for easy reference: |
| 10 | * GetExits() - return a string containing an "Obvious Exits" Statement |
| 11 | * |
| 12 | * The exits are implemented as properties P_EXITS |
| 13 | * They are stored locally (_set_xx, _query_xx) |
| 14 | * as mapping to speed up the routines in this module. |
