-OpenPGM is an open source implementation of the Pragmatic General Multicast
-(PGM) specification in RFC 3208 available at www.ietf.org. PGM is a reliable
-and scalable multicast protocol that enables receivers to detect loss, request
-retransmission of lost data, or notify an application of unrecoverable loss.
