Control Network Manager from Command Line

[Blayde <da blayde gmail com>]

I've seen that nm-tool will tell which wireless network is being used,
but is there any way to actually change/connect to a wireless network
from the command line? I've got an old laptop that I'm trying to use
w/o a gui as much as possible... Any help is much appreciated.
