This codebase is compatible with 3.1, 3.2 and 3.3. It was converted with 2to3
and a semi-automated diff/merge with packaging in 3.3 to fix some idioms.
We?ve now come full circle from 2.x to 3.x to 2.x to 3.x again :)
Starting from now, contributors can make patches for packaging (preferred, as
the stdlib?s regrtest is very useful), distutils2 or distutils-python3, and
we?ll make patches flow between versions.

Backports:
- sysconfig is now always imported from our backports
- when hashlib is not found, our backport is used instead of the md5
module (debatable; we could just drop hashlib)
Version-dependent features:
- PEP 370 features are only enabled for 2.6+
- the check for sys.dont_write_bytecode was fixed to use getattr
with a default value instead of hasattr
Idioms/syntax:
- octal literals lost their extra 0
- misused try/except blocks have been changed back to try/finally
(it?s legal in 2.4 too, it?s only try/except/finally that isn?t)
- exception catching uses the regular 2.x idiom instead of sys.exc_info
- file objects are closed within finally blocks (this causes much
whitespace changes but actually makes diff with packaging easier)
Renamed modules:
- some missed renamings (_thread, Queue, isAlive, urllib.urlsplit, etc.)
were fixed
Other:
- a few false positive replacements of ?packaging? by ?distutils2? in
comments or docstrings were reverted
- util.is_packaging regained its name
- assorted whitespace/comment/import changes to match packaging
