The documentation has currently multiple problems:
- The top left tag of the openstacktheme isn't consistent with
the latest available tag, which confuses people (see
related bug)
- There are unused variables that could deserve cleanup
- There are static content that can be discovered from files
- We don't leverage the dynamic nature of the configuration for
conditional upgrade messages, while we should.
