11/19/2002	Reviewing massive changes from Erik Rigtorp, he has added a
		userial compatible version of the passive adapter code. I am
		creating a new Makefile that will work for all systems and
		allow selection of the adapter at build time.

		Thanks for this version go to Erik Rigtorp for adding the
		userial compatible passive code. His webpage can be found
		at http://erkki.g0ds.org/

		Thanks also go out to Kevin Pedigo for his help in getting
		the new Makefile up and running. Kevin is the current
		President of KPLUG (www.kplug.org/~kevinp)

		Improved the sleep method when reading sensors multiple
		times so that it doesn't use 100 CPU while waiting. Thanks
		to peter enderborg for pointing this out.

		Changed version # to v3.0.0

08/18/2002	Added %N token to allow the time in seconds since Epoch to
bcl		be selected in the output.
		Added module for NetSaint/Nagios to perl directory, it is
		named check_digitemp.pl
		Added a MySQL logging script to perl directory, it is named
		digitemp_mysql.pl
		Added check for serial port permissions and nice error
		output if the user doesn't have +rw on the selected port.
		Removed limitation on -i being the only command. It can be
		combined with other commands again.

		Changed to v2.6

06/08/2002      Made changes suggested by John Stoffel. Consisting mostly of
                code reorganizations.
                The one new feature is the %R format specifier for the log
                output string which inserts the hex serial number of the
                sensor into the output.
                We changed the way command line arguments are processed,
                so getopt is only called once, and added a check to make
                sure only 1 of the action commands is specified and complain
                otherwise.

                Changed to v2.5

01/15/2002      Added support for DS2409 one-wire couplers like those used in
                Simon Atkin's hub. www.simat.enta.net
		Converted to Dallas Semi's userial v3.00 one-wire library.
		Version changed to v2.3
		Added a -w command to walk the entire one-wire LAN and show all
		device serial numbers with a descriptive family type.
		Thanks to Ted Frohling for the loan of the one-wire Hub.

05/28/2001	The DS18B20 and DS1822 patch was incorrect. It has been
		fixed. Version changed to v2.2

03/16/2001	Integrated the AIX changes
		Integrated the DS1822 and DS18B20 patch
		Added the patch for DS1822 and DS18B20 support.

03/13/2001	Version 2.1 release
		Added detection of a temperature glitch in the DS1820
		Added detection of the DS18S20's 85 degree C error state
		Added output of error conditions to stderr
		Bad reads will now insert zeros instead of skipping the sensor
		If a read fails it is retried 3 times before giving up on that
		sensor. The remainder of the sensors are still attempted.
		Added a command line option (-c) to allow the configuration
		file to be specified.
		Added a couple more scripts to the rrdb directory.

01/04/2000	Version 2.0 release
		Adding support for the DS9097-U adapter for the Linux
		version. The Solaris version will need changes to be able
		to support the DS9097-U.
