I hope my earlier email didn't sound too grumpy!

No, I think I was just over-stressed. I was just frantically packing
for a week in DC at pycon, preparing for a cross-country road trip
with my wife and three kids, and wanted a stable release on the web
site for the pycon presentation. I had to run to the office before we
left to do a win32 re-build to fix the win32 wx segfault, so maybe I
was a bit testy.

Pycon is fun -- met lots of good people. Now I have to head off for
more talks.

Thanks for all the hard work...
