I guess I should release this rather than sitting on it

I released version 1.0.0 of docput, a tool for pushing versioned documentation to static web hosts. It adds a menu for version selection, and uploading a version does not require rebuilding older ones. The idea is to replace ReadTheDocs with self-hosted services. It currently supports git-pages and the local filesystem, but can be easily made to work with other hosts
