+    """Usability wrapper around snow for easier development of parallel R
+       programs. This package offers e.g. extended error checks, and additional
+       functions. All functions work in sequential mode, too, if no cluster is
+       present or wished. Package is also designed as connector to the cluster
+       management tool sfCluster, but can also used without it."""
