Thank you for including the license files. Happy to merge.

Tangential question: I thought conda could install regular python packages without any modifications. Is that not true?

[mariusvniekerk]

So it certainly can, however for licenses that require distributing the license files it's preferable to have them as part of the source tarball that is on pypi.

Yes. You're correct about including the licenses file. I was just wondering about conda because you mentioned that this change was required especially for building a conda-forge package.

mostly because the conda forge maintainers ask nicely :P
