Thank you Richard, and Karl.  I'm really impressed with what I've seen
so far of Geda - why didn't I find it before?!  I've been looking for
a decent circuit diagram drawing program for quite a while and have
played with a few on the way.  I think I probably/possibly didn't find
it because it's listed as 'Electronics Design Software' in the Ubuntu
archives and gschem is 'Schematic Editor'.  Anyway, thank you all and
(I fear) expect a few more questions like the one above as I learn
about it.
