-// = DESCRIPTION
-// This is a simple test of <ACE_SV_Shared_Memory> and
-// <ACE_Malloc> using the <ACE_Shared_Memory_Pool>. The test
-// forks two processes and then executes client and server
-// allowing them to exchange data using shared memory. No user
-// input is required as far as command line arguments are
-// concerned.
