/**
* @file Multicast_Test_IPV6.cpp
*
* @brief This program tests ACE_SOCK_Dgram_Mcast class.
*
* It specifically tests subscribing to multiple groups on the same
* socket on one or more physical interfaces (if available).
*
* The test can be run as a producer, consumer, or both
* producer/consumer (default). The test requires at least two (2)
* multicast groups which can be configured as command line options.
* The consumer subscribes to a single group per instance and an
* additional instance tries to subscribe to all groups on a single
* socket (if the ACE_SOCK_Dgram_Mcast instance bind()'s the first
* address to the socket, additional joins will fail). The producer
* iterates through the list of group addresses and sends a single
* message containing the destination address and port to each one. It
* also sends messages to five (5) additional groups and a message to
* an additional port for each group in order to produce a bit of
* "noise" in order to help validate how well the multicast filtering
* works on a particular platform.
*
* The list of destination groups start at ff01::1 (default) and
* increment by 1 up to 5 (default) groups. Both of these values, as
* well as others, can be overridden via command-line options. Use
* the -? option to display the usage message...
