It’d be useful to extract dependency information from egg specifications
and setuptools snippets and somehow convert it to Nix.  The problem is
that the conversion tool would need to know the mapping between the
Python/setuptools package names and the Nixpkgs attribute names.

As for build scripts, I doubt they would be usable directly, but I’m not
familiar with these tools.

Besides, ‘buildPythonPackage’ automatically creates wrappers for
stand-alone Python applications that define the right $PYTHONPATH (see,
e.g., the ‘tahoe’ executable.)

Thanks,
Ludo’.
