I'd just like to let everyone know just how laborious this body of work
was, and say that the degree to which it was a success and seamless is a
testament to Marcus' commitment and tenacity.

Among other Big Hairy Audacious Goal's the Python@ team has kicked in
the past two quarters, this and the move to setuptools install led by
William (wg@) deserve special recognition.

So *thank you* both, on behalf of every FreeBSD/Python user, developer
and administrator who is set to benefit from your efforts.

Stand out work :)
