-		  This file collects functions related to setting multicast
-		  for multicatcher. They are IPv4 and IPv6 ready.
-		  By default, we use IPv4.
-		  To use IPv6, we need to specify -DIPv6 in Makefile.
-		  The functions in this file are collected from
-		  Richard Stevens' Networking bible: Unix Network programming
-
-		  I added Mcast_join().
