We are moving Python expressions out of pkgs/top-level/python-packages.nix into pkgs/development/python-modules/<module>/default.nix.

Please move the expression there, and call it from pkgs/top-level/python-packages.nix using callPackage ../development/python-modules/<package> { };.

@FRidh Why do we ask people to move packages? Shouldn't we move everything automatically?

@orivej any suggestion on how to do this automatically?

Reasons for moving:

1. reduce size of python-packages.nix
2. reduces merge issues
3. easier to track history
4. individual expressions can more easily be manipulated externally. E.g., I wrote maintainers/scripts/update-python-libraries.

any suggestion on how to do this automatically?

I'll experiment with a few possible approaches this weekend (mainly text manipulation based vs parser based).
