Usage:
/WORLD [-lqn] [world]
/WORLD host port
If world is already connected, "/world world" is equivalent to "/fg world", and brings world into the foreground. If world is not connected, "/world world" is equivalent to "/connect world", and attempts to open a connection to that world.
The second form is equivalent to "/connect host port".
The -lqn options are the same as those for /fg and /connect.
