+     "The Corosync Cluster Engine is a Group Communication System with additional
+features for implementing high availability within applications.  The project
+provides four C Application Programming Interface features:
+
+@itemize
+
+@item A closed process group communication model with extended virtual synchrony
+guarantees for creating replicated state machines.
+
+@item A simple availability manager that restarts the application process when
+it has failed.
+
+@item A configuration and statistics in-memory database that provide the ability
+to set, retrieve, and receive change notifications of information.
+
+@item A quorum system that notifies applications when quorum is achieved or
+lost.
