The @tellroom() function is used to display a piece of text to everyone 
in a room, or to most of a room. The first argument is the room.
The second is the player or { list of players } who shouldn't see the
message; use "-1" if everyone in the room should see it.  The third
is the text to be displayed.

@tellroom("11", "-1", "The room shakes suddenly!")
@tellroom(@location("%#"), "%#", @print(@name("%#"), " falls down."))
@tellroom("14", { *me, #1154 }, "Eeeagh!")
