Build Complete!

To run the chat-test example, open three command-windows in this directory.

cmd-window-1:
  > cd target/bin
  > java -cp chat.jar etch.examples.chat.MainChatListener 

cmd-window-2:
  > cd target/bin
  > java -cp chat.jar etch.examples.chat.MainChatClient

cmd-window-3:
  > cd target/bin
  > java -cp chat.jar etch.examples.chat.MainChatClient

cmd-window-2 and cmd-window-2 can now chat with each other !!!
