-//
-// = DESCRIPTION
-// This is a simple test of <ACE_Timer_Queue> and four of its
-// subclasses (<ACE_Timer_List>, <ACE_Timer_Heap>,
-// <ACE_Timer_Wheel>, and <ACE_Timer_Hash>). The test sets up a
-// bunch of timers and then adds them to a timer queue. The
-// functionality of the timer queue is then tested. No command
-// line arguments are needed to run the test.
-//
