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. pgm is a receiver-reliable protocol, which means the receiver is responsible for ensuring all data is received, absolving the sender of reception responsibility. pgm runs over a best effort datagram service, currently openpgm uses ip multicast but could be implemented above switched fabrics such as infiniband.

these are the debugging symbols for the library and its utilities.
