	I'm looking forward to applying this patch when you are done.

	Sounds good.  Also, there was a discussion on the list a while
ago with a statement like this from Peter Brett:

	To reiterate, I think it would be best to have a simple divide:
	stuff that's shared between geda apps goes in libgeda, stuff
	that's app-specific stays within the app itself.  However, I
	thing this is going to require a proclamation ex cathedra from
	Ales to resolve the "right way" to move forward.

I'm okay with doing just that.  App specific stuff in the app and 
code that can be/is shared in libgeda.  I don't really want to refactor
libgeda into gui and non-gui just yet.  We can do that once we have
external applications that want to use code/component that is only in
gschem now.
