+%description
+Csync2 is a cluster synchronization tool. It can be used to keep files on
+multiple hosts in a cluster in sync. Csync2 can handle complex setups with
+much more than just 2 hosts, handle file deletions and can detect conflicts.
+It is expedient for HA-clusters, HPC-clusters, COWs and server farms.
