That's good to know :-)

That's a fair argument indeed.

Well, you know, there's an important difference between making
work publicly available and giving away the source code :-)
But I get your point and do support it: It should be possible
for package authors to use different build tools than distutils.
IMO, that's easy to achieve, though, with the existing de-facto
standard interface we already have: the setup.py command line API.
We'd just need to publish the minimal set of commands and options,
installer will want to see implemented in order to initiate
