-// This test shows the use of an ACE_Auto_Event as a signaling
-// mechanism. Two threads are created (one a reader, the other a
-// writer). The reader waits till the writer has completed
-// calculations. Upon waking up the reader prints the data calculated
-// by the writer. The writer thread calculates the value and signals
-// the reader when the calculation completes.
