+ * File: pipepong.c
+ *
+ * Description:
+ * This test runs in conjunction with the pipeping test.
+ * The pipeping test creates two pipes and redirects the
+ * stdin and stdout of this test to the pipes.  Then the
+ * pipeping test writes "ping" to this test and this test
+ * writes "pong" back.  Note that this test does not depend
+ * on NSPR at all.  To run this pair of tests, just invoke
+ * pipeping.
+ *
+ * Tested areas: process creation, pipes, file descriptor
+ * inheritance, standard I/O redirection.
