I had thought that I screwed up the metadata, but it turns out I didn't.
When I discovered pip was picking the wrong version number, selecting a
four year old 0.1 version instead of the newly uploaded 0.2 version,
googling suggested that the problem might have been that I had not run

    python setup.py register

before the upload:

    python setup.py sdist bdist_wininst upload

and that re-uploading would fix the problem. So I ended up bumping the
version number so I could re-register and re-upload, but that didn't fix
the problem with pip. (Oh Google, why hast thou failed me???)

If "content" means source code and related program data, I agree, but we
should be able to adjust incorrect metadata without a version bump.

Yes please.
