Fine with me.

Actually, we've had that since top-level/python-packages.nix was added.

Yes, please remove those ‘b.’ things, changing back to the style of
top-level/python-packages.nix.

Yes, please.

Yes, please, that’d be great.  I think it doesn’t make sense to have
more than one set of Python packages, or more than one way to build
them.

OK, here’s the deal: I’ll look at the diff between the new and the
former top-level/python-packages.nix to get an idea (I find your commits
very hard to review currently since they move files around, have
misleading commit logs, and add gratuitous stylistic changes.)  I’ll
comment and commit based on that.

Can you do this?

Also, I also urge you to reply to the message at
<http://thread.gmane.org/gmane.linux.distributions.nixos/3857> so the
rest of us know what to expect.

Thanks in advance,
Ludo’.
