Hi Simon,

Your code looks good to me!

That web site (http://thedailywtf.com) is amusing in its way, but my
problem with it is that so many of the people there enjoy mocking others
in a mean-spirited and immature way.  Programming well is a hard thing.
The adolescent posturing I see there isn't admirable to me. It's also very
sad to see that, for any given bad code, there's a lot more really bad
responses.  So my feelings are mixed about it, in the same sort of way
that I have misgivings toward Slashdot.  *grin*

It's perfectly ok to take advantage of os.walk(); I like this code.


Good luck to you!
