I knew it wouldn't just be a case of moving the asd files around but
perhaps I was still underestimating the task.  Here's the problems
I've come accross so far.

1) def-c-output seems to be called defobserver now.  Is there any
semantic differences between the two?

2) make-instance 'family now requires an :fm-parent

My approach until now has been to update the cells that cells-gtk
uses, then load-system, fix errors, load-system....

I'm just communicating this in case it elicits a nugget of insight
from someone that might have attempted a similar task before.

Cheers,
Andy
