To install manually-downloaded .deb files, you can use the command
	dpkg -i yourpackage.deb
dpkg won't install dependencies though, so if it complains about something 
being missing, you'll want to run

If you're running testing, a better option is to use gdebi

	dip	(for modems)
	games	(anyone can play games, this is just to save scores)
	lpadmin	(change printer settings)
