[Catalog-sig] licensing and accessability of code on pypi

The author of the package is clearly confused with respect to
licensing.  It appears he's using CC Attribution-Non Commercial which
allows unlimited, non-commercial redistribution.  If you release
something under a CC license, you can't also required permission for
redistribution.  We also specifically discourage the use of CC
licenses for software -- they just weren't designed for that purpose
and there are lots of excellent open source/free software licenses
that were.

For what it's worth.
