Uploading to PyPI

Yesterday, my co-worker, Tom Christie, posted a guide on uploading Python modules to PyPI. I’ve done this a few times, but haven’t had to deal with a package as complicated as the one he was uploading, since the packages I’ve uploaded are pure Python. His package compiles a C program which gets called by the Python library, and provides some pickled data to minimize recomputation.

One thing I noticed was the suggestion to use twine to minimize transmission of PyPI passwords in plaintext. I’m not sure why pip doesn’t use HTTPS to interact with PyPI directly, but I suspect this to be fixed upstream before too long. For now, twine provides a workaround.
