/*! \addtogroup loggingrb
* @{
* This adds a log which consist of an in-memory ring buffer. The idea
* is that the user can configure his logging in a way that critical
* messages get stored in the ring buffer, and that the last few
* critical messages can then always obtained by dumping the ring
* buffer. It can hence be used as a more generic version of the
* "show me the last N alarms" functionality.
