Hence something like xml for a prototype and discussion - I did not
suggest to use xml for the end product package. I have as much love for
xml as the next python guy.

I think nested conditions for configurations is a must-have. Once you
have more than 2-3 variables, doing it like PEP 390 is not really
manageable. Particularly for C extensions, having many configurations is
quite common in my experience.

I don't think python 1.5 should be considered - I happen to contribute
to scons, which is a build tool in python, and supports all python
versions from 1.5.2: the 1.5 requirement is a real downside. You can't
use list comprehension, you need apply instead of f(*args, **kw), you
don't have subprocess for reliable process execution, and I am not even
talking about testing.
