+or distant commands in parallel on server farms or on large GNU/Linux
+clusters.  It will take care of common issues encountered on HPC clusters,
+such as operating on groups of nodes, running distributed commands using
+optimized execution algorithms, as well as gathering results and merging
+identical outputs, or retrieving return codes.  ClusterShell takes advantage
+of existing remote shell facilities such as SSH.")
