+ * [Description]
  *
- * DESCRIPTION
- *      Verify that,
+ * Test for checking error conditions for getrlimit(2)
  *   1) getrlimit(2) returns -1 and sets errno to EFAULT if an invalid
  *	address is given for address parameter.
  *   2) getrlimit(2) returns -1 and sets errno to EINVAL if an invalid
  *	resource type (RLIM_NLIMITS is a out of range resource type) is
  *	passed.
- *
- * Setup:
- *   Setup signal handling.
- *   Pause for SIGUSR1 if option specified.
- *
- *  Test:
- *   Loop if the proper options are given.
- *   Execute system call
- *   Check return code, if system call failed and errno set == expected errno
- *		Issue sys call fails with expected return value and errno.
- *      Otherwise,
- *		Issue sys call failed to produce expected error.
- *
- *   Cleanup:
- *	Print errno log and/or timing stats if options given
- *
- * USAGE:  <for command-line>
- *  getrlimit02 [-c n] [-e] [-i n] [-I x] [-P x] [-p] [-t] [-h]
- *     where,  -c n  : Run n copies concurrently.
- *		-e   : Turn on errno logging.
- *		-i n : Execute test n times.
- *		-I x : Execute test for x seconds.
- *		-P x : Pause for x seconds between iterations.
- *		-p   : Pause for SIGUSR1 before startingt
- *		-t   : Turn on syscall timing.
- *		-h   : Display usage information.
- *
