Setuptools has been relicensed under the MIT license.
As noted in that commit message, the bundled modules are under different licenses. Since upstream version 26.1.0, there are four bundled modules.
packaging - BSD or ASL 2.0
pyparsing - MIT
six - MIT
appdirs - MIT
Please update the License tag in the spec file to reflect these changes.
Note that as of http://setuptools.readthedocs.io/en/latest/history.html#v34-0-0 setuptools no longer bundles those modules.
Fixed and mailed devel list on license change.
Thanks for the note!
