+* Revision 1.4 2005/05/04 17:54:00 mridge
+* Update to version 1.2.8
+*
+* Revision 1.4 2002/03/30 01:32:14 yardleyb
+* Major Changes:
+*
+* Added Dumping routines for
+* data miscompares,
+*
+* Updated performance output
+* based on command line. Gave
+* one decimal in MB/s output.
+*
+* Rewrote -pL IO routine to show
+* correct stats. Now show pass count
+* when using -C.
+*
+* Minor Changes:
+*
+* Code cleanup to remove the plethera
+* if #ifdef for windows/unix functional
+* differences.
+*
+* Revision 1.3 2002/02/21 21:32:19 yardleyb
+* Added more unix compatability
+* ifdef'd function out when
+* compiling for unix env. that
+* have getopt
+*
+* Revision 1.2 2002/02/04 20:35:38 yardleyb
+* Changed max. number of threads to 64k.
+* Check for max threads in parsing.
+* Fixed windows getopt to return correctly
+* when a bad option is given.
+* Update time output to be in the format:
+* YEAR/MONTH/DAY-HOUR:MIN:SEC
+* instead of epoch time.
+*
+* Revision 1.1 2001/12/04 18:57:36 yardleyb
