Support multiple doc versions?

[tyralla]

Hello everyone!

Just a question: Would it be possible to implement documentation versioning into travis-sphinx (or is it already implemented)?

At the moment, my doc on GitHub Pages is based either on my master branch or on my develop branch. It would be great to be able to select between the docs of both branches (or to select between the docs of different tags). I mean something like the official Python documentation, where you have access to some of the latest versions and the current development version.

Or should I restrict GitHup Pages on my master branch and consider documenting different tags on Read the Docs instead?
