There are various repositories available; always in a "normal" version, containing the latest stable releases
or release candidates, and a "nightly" version, build after every change.
The repositories are also available on build.opensuse.org in the
home:stbuehler: namespace,
containing packages for additional distributions (openSUSE, Fedora, Ubuntu).
