+  <longdescription>
+    The library has modular design: its core part implements only the core 
+    Raft algorithm logic, in a fully platform independent way. On top of that, 
+    a pluggable interface defines the I/O implementation for networking 
+    (send/receive RPC messages) and disk persistence (store log entries and 
+    snapshots).
