  * This is a thread-safe, multicast DIS network interface class which greatly simplifies reading and writing of PDUs for applications.
+ * This simplifies and consolidates all reading, writing and threading of DIS over the network.
  * 
  * Example <code>main()</code> self-test response shown in log file.
