In CDL you can have a requires statement that at least one device is
enable. Hopefully there will then be a conflict to indicate to the
user something is wrong. The danger is the inferance engine will solve
the conflict by simply enabling one of the devices. The one it picks
may however not be the one the user wants. When using ecosconfig this
will be clear, since it prints what inferences it has made. I don't
use the configtool, so i don't know if it throws up a dialog box
showing its inferences?
