  * DESCRIPTION
  *	semctl01 - test the 10 possible semctl() commands
  *
- * ALGORITHM
- *	create a semaphore set with read and alter permissions
- *	loop if that option was specified
- *	  loop through the test cases
- *	    do any setup required for the test case
- *	    make the semctl() call using the TEST() macro
- *	    check the return code
- *	      if failure, issue a FAIL message.
- *	    otherwise,
- *	      if doing functionality testing
- *		call the appropriate test function
- *	  	if correct,
- *			issue a PASS message
- *		otherwise
- *			issue a FAIL message
- *	call cleanup
- *
- * USAGE:  <for command-line>
- *  semctl01 [-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.
