20 * The OpenRTE Group Communications
21 *
22 * The OpenRTE Group Comm framework provides communication services that
23 * span entire jobs or collections of processes. It is not intended to be
24 * used for point-to-point communications (the RML does that), nor should
25 * it be viewed as a high-performance communication channel for large-scale
26 * data transfers.
