- @open <exit name>[;<exit aliases>][=<destination dbref>[,<exit back>;<exit aliases>]]
This command opens an exit in the room you are standing in with the specified name and exit aliases. You can then use the @link command to set the exit's destination, or you can set it at the same time by providing the dbref of a destination. If you provide the destination, you can also optionally give the name for an exit back from the destination room to the source room along with its exit aliases.
Exits may only be @open'd from rooms. You must control a room to @open an exit from it. Destinations may be rooms or things. If you give a destination, you must control the destination or it must have the Link_Ok flag.
