There were a couple of issues that accidentally made it through in #1151.

In my understanding, the reasons for these changes are:

• We're still including a LICENSE, because the contents of license-files are automatically included without manually specifying it in MANIFEST.in: https://packaging.python.org/en/latest/guides/using-manifest-in/
• We don't need to manually list README because it doesn't exist, and README.md is automatically included
• zip-safe is obsolete (https://setuptools.pypa.io/en/latest/deprecated/zip_safe.html) so we can delete it.

Let me know if that's correct. Approving.

[vyasr]

You're right about the first two. You're also right about zip-safe being deprecated, but we decided that we should keep it for safety until we move all the way away from setuptools. I didn't delete it, I moved it from pyproject.toml to setup.py because that is one of the keys that don't work in pyproject.toml with scikit-build.

I moved it [zip-safe] from pyproject.toml to setup.py because that is one of the keys that don't work in pyproject.toml with scikit-build

Ah ok. Good to have this context. Thanks Vyas! 🙏
