 /*
- * NAME
- *	open01.c
- *
  * DESCRIPTION
  *	Open a file with oflag = O_CREAT set, does it set the sticky bit off?
- *
  *	Open "/tmp" with O_DIRECTORY, does it set the S_IFDIR bit on?
  *
  * ALGORITHM
  *	1. open a new file with O_CREAT, fstat.st_mode should not have the
  *	   01000 bit on. In Linux, the save text bit is *NOT* cleared.
- *
  *	2. open "/tmp" with O_DIRECTORY.  fstat.st_mode should have the
  *	   040000 bit on.
- *
- * USAGE:  <for command-line>
- *  open01 [-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
