WARNING!

This script includes example code from the Lean Prover community, who
used this repo to store the Zulip content as well as the code.  We
recommend to most folks to create a **separate** repo for your
content, even if you are using Github to serve the content, and expect
to convert this tool to a supported option based on that model.
