It turns out that our current setup does not really support the `sdist`
Python packaging step. I'm trying to increase automation, both for
making releases for upload to pypi.org, and also for CI via Zuul. As it
turns out, Zuul comes with a set of predefined jobs which -- by default
-- use `tox`, and tox was having troubles dealing with our `setup.py`
because it also assumes that the `sdist` step works. It is also supposed
to:
- fix version number duplication in `setup.py`,
- fix version number duplication in Sphinx docs,
- prevent the need to write a `MANIFEST.in` manually.
TL;DR: insetad of having to deal with a ton of other creative
boilerplate, use tools for lazy people like me, and PBR ("Python Build
Reasonableness") appears to check the marks here.
