A combination of the two, actually.  I've used both David's script and 
yours in concert.  In addition, I've modified David's script to color 
the nodes based on origination, and to exclude or collapse 'Base' and/or 
'required-by-Base' packages.

I've got a few cleanups, and then I'll share the result.  It's already 
helped me generate a few re-packaging requests I plan to post over on 
cygwin-apps...
