  * Expected Result:
  *  chmod() should return value 0 on success and succeeds to set sticky bit
  *  on the specified file.
- *
- * Algorithm:
- *  Setup:
- *   Setup signal handling.
- *   Create temporary directory.
- *   Pause for SIGUSR1 if option specified.
- *
- *  Test:
- *   Loop if the proper options are given.
- *   Execute system call
- *   Check return code, if system call failed (return=-1)
- *   	Log the errno and Issue a FAIL message.
- *   Otherwise,
- *   	Verify the Functionality of system call
- *      if successful,
- *      	Issue Functionality-Pass message.
- *      Otherwise,
- *		Issue Functionality-Fail message.
- *  Cleanup:
- *   Print errno log and/or timing stats if options given
- *   Delete the temporary directory created.
- *
- * Usage:  <for command-line>
- *  chmod07 [-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.
