Missing files in sdist

[thatch]

It appears that the manifest is missing at least one file necessary to build
from the sdist for version 0.2.33. You're in good company, about 5% of other
projects updated in the last year are also missing files.

It would appear this doesn't happen with current versions of setuptools/pip on a repo build.
