There are three phases to this tutorial:

1. Building a Color Belot application without a user interface and without networking capabilities.  Select the "Application" link.
2. Converting the application developed in the previous phase to an applet and adding a user interface.  Select the "User Interface" link.
3. Adding networking capabilities to the applet developed in the previous phase so that there can be one server and two clients.  Select the "Network" link.
