+Member example shows how you can build a simple multicast group 
+using transactional multicast (TMCast). Each member can be either 
+a sender or a receiver.
+
+The sender sends small messages to the multicast group with a random 
+wait period in [0, 1] second range. The receiver is simply receiving
+those messages and prints them out.
+
+To start the sender you can execute something like this:
+
+$ ./member s sender-1 239.255.0.1:10000
+
+Here the first argument ('s') indicates that new member will be
+a sender. The second argument ('sender-1') is an id of the new
+member (each member of the group should have a unique id). And 
+the third argument ('239.255.0.1:10000') specifies IPv4 multicast 
+address and port (you can choose you own).
+
+To start the receiver you can execute similar command:
+
+$ ./member r receiver-1 239.255.0.1:10000
+
+After you have started both the receiver and the sender you
+should see a sequence of messages printed by the receiver.
+
+Note, since the group can exist with only one member for a 
+very short period of time you should start first two members
+virtually at the same time. See TMCast documentation for more
+information about why it behaves this way.
+
+You may want to add more than one sender to the group if you
+want to see how TMCast operates in a totally-ordered mode.
