	- changed order in which settings are applied:  placed standby last
hdparm-2.0:
	- added this file to the distribution
	- added -f and -q flags to hdparm.c and hdparm.8
	- added -N to gcc in makefile
	- changed installation paths to /usr/local/* in makefile
	- removed meaningless CPU% measures
	- removed -s and -x flags
	- added new -AKPSWXZ flags using new HDIO_DRIVE_CMD ioctl
	- removed BLKFLSBUF ioctl from everywhere except -t
	(there may be a kernel bug in the implementation of BLKFLSBUF
	 when used on an active (mounted rw) filesystem).
	- most features now require (E)IDE driver v2.6 or higher
	(ide-2.6.patch.65+.gz)
