@set here=abode. If a room is set ABODE, players can set their homes there, and can set the homes of objects there. (LINK_OK is now used only for exits, and ABODE is for players and objects.) When set on a program, it means AUTOSTART. This means that when the game is first started up, the program will automatically be run with a trigger of #-1 and a 'me @' of the owner of the program. This is useful to restart processes that run in the background periodically.
