    # We have two and a half types of builds: Wheel builds run on all supported
    # platforms and run the basic test suite for all supported python versions.
    # Sdist builds (the "and a half") just build an sdist and run some basic
    # validation. Both of these upload their artifacts to pypi if there is a
    # tag on the build and the key is available.
    #
    # Tox builds run a more comprehensive test suite with more configurations
    # and dependencies (getting all these dependencies installed for wheel
    # builds is a pain, and slows things down because we don't use as much
    # parallelism there. We could parallelize wheel builds more but we're also
    # amortizing download costs across the different builds). The wheel builds
    # take longer, so we run them before the tox builds for better bin packing
    # in our allotted concurrency.
