I forgot to add the [1] here, but it’s basically that `python setup.py sdist —formats=` actually errors out, because an empty str is not a valid format, but it errors out *after* distutils has prepped an unpacked directory and the only things left are (A) taring up that unpacked directory into the desired formats and (B) deleting that unpacked directory. Neither of which we want to do in this case. — Donald Stufft
