//
// = DESCRIPTION
// This is a simple test of Named Pipes that uses
// ACE_SPIPE_Acceptor and ACE_SPIPE_Connector classes. The test
// forks two processes or spawns two threads (depending upon the
// platform) and then executes the client and server allowing
// them to use the named pipe to exchange data. No user input is
// required as far as command line arguments are concerned.
