The pytables documentation (www.pytables.org) is hosted via GitHub pages from the PyTables/pytables.github.com repo. The PyTables docs are build from the main repo and push to PyTables/pytables.github.com by travis-CI at every release/tag.
This repo is also published using Github pages and contains static files (pdfs and such) that are not built from the main repo, but are linked to.
