incorrect use of setup's 'license' kwarg
"The license field is a text indicating the license covering the package where the license is not a selection from the “License” Trove classifiers."
i.e. The value of the license keyword arg shouldn't be a filename, it should be the name of a license, and it should probably be specified using the trove classifiers instead of using the 'license' keyword arg.
I hope I haven't misinterpreted - I'm no expert, but thought I'd submit what looks like an error to me.
