+SYNOPSIS
+        void exit(object ob)
+
+DESCRIPTION
+        This function was used in compat mode drivers in context
+        with moving objects. Nowadays objects are moved by means
+        of the H_MOVE_OBJECT0/1 hooks, and use of this lfun is
+        up to the mudlib.
+
+        This function was called in the old environment everytime a
+        living object ob leaves it.
+
+        The function this_player() will return a random value, don't
+        use it at this point.
+
+        WARNING: Using this function is EXTREMELY dangerous. A single
+        bug, and you are forever (i.e. until the next reboot occurs)
+        caught in the room.
