I was reading the MANIFEST.in file, and found this line:

https://github.com/theacodes/nox/blob/7443a93582a47a7dc680d90d6afeb686368e3985/MANIFEST.in#L1

However, https://packaging.python.org/guides/using-manifest-in/#how-files-are-included-in-an-sdist says that the license file defined by license_file (at setup.cfg) is included by default by newer versions of Setuptools. The license_file is:

https://github.com/theacodes/nox/blob/7443a93582a47a7dc680d90d6afeb686368e3985/setup.cfg#L11

I just want to know if the MANIFEST.in inclusion is redundant in our case, since I don't know how does build includes files. Also, if that's the case, I offer to open a PR to fix that.
