michael@0:  *
michael@0:  * Description:
michael@0:  * This test runs in conjunction with the pipepong test.
michael@0:  * This test creates two pipes and redirects the stdin and
michael@0:  * stdout of the pipepong test to the pipes.  Then this
michael@0:  * test writes "ping" to the pipepong test and the pipepong
michael@0:  * test writes "pong" back.  To run this pair of tests,
michael@0:  * just invoke pipeping.
michael@0:  *
michael@0:  * Tested areas: process creation, pipes, file descriptor
michael@0:  * inheritance, standard I/O redirection.
