Comment 1 for bug 588782

I abandoned this originally proposed change as someone on IRC pointed out that the keywords and categorization are linked with others' work, and probably should remain for posterity at least.

I still feel that the package metadatas are inconsistent and could use a bit of cleanup, which is why I originally used a broad subject for this bug.

Some packages have no categorization data at all, and while many include at least their main, if not all of their, doctests in the long_description for PyPI, so I'm going to kick out some changesets to make this more consistent.
