+ * File: pipepong2.c
+ *
+ * Description:
+ * This test runs in conjunction with the pipeping2 test.
+ * The pipeping2 test creates two pipes and passes two
+ * pipe fd's to this test.  Then the pipeping2 test writes
+ * "ping" to this test and this test writes "pong" back.
+ * To run this pair of tests, just invoke pipeping2.
+ *
+ * Tested areas: process creation, pipes, file descriptor
+ * inheritance.
