Because that's what it does. It connects to a bunch of ttys, allows you 
to type in it's "shell", and stuffs a copy of what you type out to all 
of the ttys it's connected to. It monitors each "connection" through 
individual xterms. Near as I can tell, it's for people that are too lazy 
to cut/paste. :-)
