-/*
- * NAME
- *	rename01
- *
- * DESCRIPTION
- *	This test will verify the rename(2) syscall basic functionality.
- *	Verify rename() works when the "new" file or directory does not exist.
+/*\
+ * [DESCRIPTION]
  *
- * ALGORITHM
- *	Setup:
- *		Setup signal handling.
- *		Create temporary directory.
- *		Pause for SIGUSR1 if option specified.
- *
- *	Test:
- *		Loop if the proper options are given.
- *              1.  "old" is plain file, new does not exists
- *                  create the "old" file, make sure the "new" file
- *                  dose not exist
- *                  rename the "old" to the "new" file
- *                  verify the "new" file points to the "old" file
- *                  verify the "old" file does not exist
- *
- *              2.  "old" is a directory,"new" does not exists
- *                  create the "old" directory, make sure "new"
- *                  dose not exist
- *                  rename the "old" to the "new"
- *                  verify the "new" points to the "old"
- *                  verify the "old" does not exist
- *	Cleanup:
- *		Print errno log and/or timing stats if options given
- *		Delete the temporary directory created.
- *
- * USAGE
- *	rename01 [-c n] [-f] [-i n] [-I x] [-P x] [-t]
- *	where,  -c n : Run n copies concurrently.
- *		-f   : Turn off functionality Testing.
- *		-i n : Execute test n times.
- *		-I x : Execute test for x seconds.
- *		-P x : Pause for x seconds between iterations.
- *		-t   : Turn on syscall timing.
- *
- * HISTORY
- *	07/2001 Ported by Wayne Boyer
- *
- * RESTRICTIONS
- *	None.
+ * Verify rename() when the newpath file or directory does not exist.
