Added tag 2.2 for changeset 39f7ef5ef221
Bumped to 2.3 in preparation for next release.
Do not override _bytecode_filenames

The overridden version cannot handle Python 3.x while distutils verion can
handle it just fine.
Update changelog
Adding comment referencing #134.
More succinctly implement declare_state.
Move comments
Simplify syntax of for loop
Moved master working set construction into classmethods of WorkingSet.
I checked this syntax, then failed to update the code before committing.
Neglected to remove another reference to the global 'working_set'
Remove debug code, unintentionally committed.
Normalize indentation in docstrings and function params
Replace _extractall with the canonical TarFile.extractall.
Don't eagerly import namespace packages.  This was the big reason for
branching to 0.7 now, as I wanted this wart gone before anything went
into Python 2.5.  But it's gone now, yay!
Namespace package doc tweaks.
Bumped to 3.0 in preparation for next release.
Declare support for Python 3.4
Use zip files rather than tar files for source distributions of setuptools itself. Fixes #7 for users of Python 2.7.4 and later.
Extract 'archive_context' from _install and _build_egg
