Why not use 'pypi-uri' here? Otherwise LGTM.

What would that give us?

Good question. Pypi archives are sometimes smaller than the raw sources
or otherwise "prepared", but I guess no inherent benefits.

From what I can tell, GitHub automatically generates snapshot tarballs
of Git tags. These tarballs are usually not real "release" tarballs that
have been prepared by the upstream maintainers. Sometimes this isn't the
case, but it seems to be for these "untitled" v$version.tar.gz tarballs.

We have tools to automatically update packages fetched from PyPi.

And using pypi-uri removes another URL that we need to maintain.

Is there a reason not to use PyPi?

Oh, I didn't know that.

Good point. I can certainly see people relying too heavily on GitHub
(and similar) tarball auto-generation, while uploading a better one to
PyPI that they've actually bootstrapped.

Since this one builds fine, and the GitHub project is the official home
page for better or worse, I'd vote against adding an ‘additional
dependency on PyPI infrastucture’ as I think someone on the list put it.

A glance at the Guix commit log suggests you're far more knowledgable
than I about anything Python, though.

Kind regards,

T G-R

Another reason for using pypi is that the github updater ignores tagged 
but not released 'releases', such as this. Perhaps we should change 
that, do others have an opinion?

Since using pypi is the way Python users expect to be able to install 
packages, making developers less concerned about their github releases 
than their pypi ones, I reckon sticking with pypi-uri is the way to go.

I'm not a Python programmer and have never used PyPI. The one time I did
try to use it as a one-stop update shop, it turned out to be out-of-date.

I'll adjust accordingly and push. Thanks (everyone) for the useful
feed-back!

Kind regards,

T G-R
