 This package contains the reliable multicast framework run-time library
 for ACE.
 .
 ACE_RMCast is a simple, small-scale reliable multicast framework for
 ACE. The framework is based on the ASX components of the ACE library:
 the protocol is implemented as a stack of interchangeable "modules",
 each one in charge of a very small task. For example, one module
 implements fragmentation and reassembly, other modules implement
 retransmission, send ACK and NAK messages, and maintain receiver
 membership.
