I wrote check-manifest for this.
Prior to that I used to have horrific Makefile rules that did a similar check:

I wrote restview for a different purpose, but found it rather useful for
discovering ReStructuredText problems that would make PyPI's fall back
to plaintext rendering.
If you run
in a directory containing a setup.py, it'll invoke `python setup.py
--long-description' and interpret it using the same docutils settings as
PyPI, highlighting any errors.
For a more automated (but perhaps less accurate) solution I pipe
python setup.py --long-description | rst2html > /dev/null
in my Makefile:

I'm really happy with being able to make releases of any of my packages
This runs the test suite (tox/detox FTW), checks for uncommitted
changes, makes sure MANIFEST.in is correct, makes sure the version
number in setup.py matches the version number in CHANGES.rst (and
release date is today), makes sure there are no RST errors in
long_descrption, and reminds me the commands I need to run to creates a
version control system tag and package + upload the sdist to PyPI. (I'm
too paranoid to let automated tools perform externally-visible actions
like uploading to PyPI or pushing git tags, so I just copy & paste the
commands once I'm sure everything's ship-shape.)
There are other excellent tools for this (e.g. zest.releaser). One day
I'll get tired of copy-pasting my Makefiles from project to project and
I'll switch to zest.releaser.

I'm not sure what you mean. Do you have any examples?
