no one really wants to make a new standalone release of Distutils.
Given that, there's no reason for Distutils code to preserve backward
compatibility, so I am removing the requirement for 2.1 compatibility.
(Jython doesn't use Distutils. Samuele Pedroni observes that if
Jython does use it someday, that version of Jython will likely support
2.2/2.3 features. So Jython isn't a reason to keep 2.1
compatibility.)
Guido wants a comment at the top of each file that has a compatibility reqt
Remove modulefinder as having a compatibility reqt
(I think this is what Guido and Thomas agreed to, let me know if not.)
