It looks like we'll also need to update the documentation link, plus make sure travis builds stuff and pushes it to the right place.

EDIT: I had a quick skim through the CI stuff and it looks like we'll need to update the following for travis:

• ci/deploy.sh
• .travis.yml secret key

I also did a quick grep through the documentation for anything mentioning "azerupi" (rg azerupi | wc) and there are 30-odd link which will need to be updated at some point. They're mainly in the documentation though, so we can leave it for a later PR.

Oh yeah, I mostly wanted to see that Travis is still running :) More to do, of course.

[Michael-F-Bryan]

I'm pretty sure travis should still run because the git user details and GH_TOKEN being used in ci/deploy.sh stayed the same. I'll create another issue to deal with updating links and stuff.

@steveklabnik, it looks like travis and GitHub Pages are working so do we still need this PR?

[steveklabnik]

We don't; we should fix all of these links at once like in the other PR.

Sorry for the late response here, I've been on vacation! Back now though.
