"""
This is a quick-and-dirty script to upload release assets to Github via the API.
Currently, we do not use this script and rely instead on the github-release binary. This
is just in case the github-release binary stops working (as it has before).
Run script with:
GITHUB_TOKEN=s3cr3t ./github-release.py v3.00.00 ./dist/tutor-openedx-3.00.00.tar.gz "tutor-$(uname -s)_$(uname -m)"
