Looks ok. Thanks for adding these shenanigans so that we can conserve precious page rules.

Does this script run whenever the docs on master are rebuild?

@lilyminium please merge yourself whenever you feel this is ready. I assume you'd want to monitor closely what's happening when the merge occurs.

Does this script run whenever the docs on master are rebuild?

It gets run on the success of building docs on Travis, on merge -- or I think you could manually do it with deploy_docs_via_travis.sh?

Edit: but only for a version without "dev" in the name
