+// Description:
+// e32test\active\t_idle.cpp
+// Overview:
+// Test the CIdle class. A CIdle and CTimer run on the same active scheduler and
+// the test displays how their callback function and RunL respectively are called.
+// API Information:
+// CIdle 
+// Details:
+// - Create and install active scheduler.
+// - Create and start a timer, add this to the active scheduler, request an event
+// after a specified interval. The timer will reschedule itself for a finite
+// number of times, then it will cancel the CIdle object and then reschedule
+// itself again and eventually it will stop the active scheduler.
+// - Create a CIdle active object, start a background task that is encapsulated in
+// callback function. The CIdle will keep reschedule itself by always returning
+// TRUE from the callback.
+// - Output some text from timer's RunL and CIdle's callback to show when they are
+// called and how they interleave.
+// Platforms/Drives/Compatibility:
+// All.
+// Assumptions/Requirement/Pre-requisites:
+// Failures and causes:
+// Base Port information:
+//
