openSUSE Build Service (OBS) has a problem. It is horrible powerful, but no one knows. Or no one knows how to make use of it in short.
Our documentation exists only in the wiki so far. While the wiki is still and will remain as a documentation resource, several of us OBS users and developers think we need something more structured and edited. A real book in short, which you can read to get an entire overview.
Therefore we started to create the infrastructure to write such books, it is part of the openSUSE documentation project. This means the documentation is written in docbook and hosted in svn.
