Description

Looking into some distutils deprecation processes I noticed that its code has been merged in w/o any copyright/licensing information retained. I think this needs to be fixed. IANAL tho.

Relicensing it as MIT seems fine for as long as the terms and conditions of the PSF license are met.

Expected behavior

https://docs.python.org/3/license.html seems to imply that the PSF copyright is mentioned and the changes described. Specifically:

2. [...] PSF hereby
   grants Licensee a [..] license to
   [...], prepare derivative works,
   distribute, and
   [...], however, that PSF's License Agreement and PSF's notice of
   copyright, i.e., "Copyright © 2001-2021 Python Software Foundation; All Rights
   Reserved" are retained in Python 3.9.5 alone or in any derivative version
   prepared by Licensee.

3. In the event Licensee prepares a derivative work that is based on or
   incorporates Python 3.9.5 or any part thereof, and wants to make the
   derivative work available to others as provided herein, then Licensee hereby
   agrees to include in any such work a brief summary of the changes made [...]

Thanks. Probably this applies more appropriately to pypa/distutils than pypa/setuptools. Please consider applying any fix there (and it will get merged here).

What about https://github.com/pypa/setuptools/tree/main/setuptools/_distutils? Is it merged in from that repo?

Is it merged in from that repo?

Yes, exactly.

Note that distutils repo as a LICENSE file but https://github.com/pypa/setuptools/tree/main/setuptools/_distutils is the disutils subfolder from that repo. So the LICENSE file from distutils is not imported into https://github.com/pypa/setuptools/tree/main/setuptools/_distutils.
