The License field for python-grabbit has been updated from “MIT” to “MIT
AND Unlicense” to reflect the _version.py file generated by Versioneer 0.29.
As described in
https://github.com/python-versioneer/python-versioneer#license, the
_version.py file generated by Versioneer is under the same license as
Versioneer itself. Since Versioneer 0.24, this is Unlicense; before
that, it was CC0-1.0, or in much older versions, a public-domain
declaration represented as LicenseRef-Fedora-Public-Domain.
