Usage: open [direction] door
Open command is used to open doors in a given room. If the room just has only one door it can be used without [direction] argument, otherwise you should refer which door to open. [direction] should be the exit where the door is (it's called direction to mean "north", "south", etc, but for instance an exit "enter" may have a door, and thus you should use "enter" as direction).
