 /**
+ * This application is used to test the basic functionality of the printf service.  
+ * It is initiated by calling the start() command of the SplitControl interface 
+ * provided by the PrintfC component.  After starting the printf service, calls to 
+ * the standard c-style printf command are made to print various strings of text 
+ * over the serial line.  Only upon calling PrintfFlush.flush() does the data 
+ * actually get sent out over the serial line.
