Thanks Bengt - that looks great.  You really should be on the payroll.

I won't have time until tonight to wrap my head around your code, but
I think I'll add a to_dot method to the Node class which generates dot
output, so I can use your ascii output for day-to-day stuff, and then
go to dot for publication quality.

Thanks all for the suggestions,
