I actually have a patch for this in a WIP tree (attached). Based on the
differences, and the fact that I have already made the changes requested
below, I think my version of the patch should be used. My patch also
adds a python-2 version; when possible, it's preferred to add both
versions.

What do you think?

I'm glad to see we concur on this.

I don't believe that unittest2 is needed. I can build both
python-variants without it.

Setuptools is only needed for the python2-variant.

And, I think mock is only needed at build-time, so it would be a
native-input.

Generally descriptions should be more descriptive than the synopsis.

I believe the license is lgpl3+, based on the "or later version" in
mpd.py.
