+// Description:
+// e32test\active\t_asyc.cpp
+// Overview:
+// Exercise the priority mechanism of active objects whereby active 
+// objects are run in the priority order.
+// API Information:
+// CAsyncOneShot, CActiveScheduler.
+// Details:
+// - Install active scheduler.
+// - Create active objects of different priorities and verify their RunL 
+// is called in the priority order.
+// - Verify that a very low priority active object will not get the chance
+// to run if a higher priority object keeps rescheduling itself or a 
+// higher priority object stops the active scheduler.
+// Platforms/Drives/Compatibility:
+// All.
+// Assumptions/Requirement/Pre-requisites:
+// Failures and causes:
+// Base Port information:
+// 
+//
