Frank and Bruno,
Some of the test 'main' functions in the library modules are out of
date - they were the basis of the example programs and I stopped
updating them once the examples were working. Try urltree1.py rather
than urltree.py. I'll be online more on Sunday and much more starting
on Monday once I get to NetSci 2009 in Venice, so I can help more
then. Thanks again fro helping Frank, Bruno!
Dale
