 /**
- * CADClient is the main class for the CAD Client application. The main method
- * instantiates an instance of the CADClient object with the default properties
- * file "..\config\CADClient.properties" or the first argument fom the command
- * line invocation. Properties data values are used to bind socket communication
- * between the CAD Client and the CAD Simulator. The CADClientModel object is
- * instantiated and the CAD Client registers itself with the CAD Simulator.
- * Finally, the CADClockView is initialized, the model-view and observer
- * relationships are established, and the view is shown.<br>
- * <br>
- * The properties file contains the following data: <br>
- * <code>
- * -----------------------------------------------------------------------------<br>
- * Host Name The host name where the CAD Simulator is located.<br>
- * Port Number The port number that the CAD Simulator is bound on.<br>
- * CAD Position The integer (>= 0) position for this CAD Client.<br>
- * CAD User ID The unique user id for this CAD Client.<br>
- * Error File Filename of error logging file.<br>
- * -----------------------------------------------------------------------------<br>
- * Example File: <br>
- * CADSimulatorHost = localhost<br>
- * CADSimulatorSocketPort = 4444<br>
- * CADPosition = 1 <br>
- * CADUserID = A12345<br>
- * ErrorFile = cad_client_err.txt<br>
- * </code>

- * @version $Date: 2009/04/17 16:27:47 $ $Revision: 1.8 $
+ * CADClockDisplay shows the simulation clock time. It operates as a client of
+ * the CAD server, using RMI to poll the server every second for the current
+ * simulation clock time.
