		Google Summer of Code 2007 @ The FreeBSD Project
	Porting OpenBSD's sysctl Hardware Sensors framework to FreeBSD
			(2007-256, a 23-y.-o. edition)


Description:

	On this 256th day of 2007,   it is my great pleasure to
	present a feature-complete port of the hardware sensors
	framework from OpenBSD to FreeBSD.

	Below is a complete `cvs diff` of cnst-sensors GSoC2007
	project as of 2007-256.

	It includes the following components,  listed below in
	the very same order as they are appearing in this diff:

	* sample configuration file for sensorsd
	* rc(8) script and glue code for sensorsd(8)
	* sysctl(3) doc fixes for CTL_HW tree
	* sysctl(3) documentation for hardware sensors
	* sysctl(8) documentation for hardware sensors
	* assorted KNF and bug-fixes for sysctl(8)
	* support for the sensor structure for sysctl(8)
	* coretemp(4) documentation
	* it(4) documentation
	* lm(4) documentation
	* rc.conf(5) documentation for starting sensorsd(8)
	* sensor_attach(9) et al documentation
	* coretemp(4) conversion to the hw.sensors framework
	* it(4) isa driver ported from OpenBSD
	* lm(4) isa driver ported from OpenBSD
	* /sys/kern/kern_sensors.c
	  o sensor_attach(9) API for drivers to register ksensors
	  o sensor_task_register(9) API for the update task
	  o sysctl(3) glue code
	  o hw.sensors shadow tree for sysctl(8) internal magic
	* assorted KNF and bug-fixes for /sys/kern/kern_sysctl.c
	* it(4) module for testing sensor_attach/detach et al
	* lm(4) module for testing sensor_attach/detach et al
	* <sys/sensors.h>
	* assorted bug-fixes and HW_SENSORS definition for <sys/sysctl.h>
	* sensors display for systat(1), including all documentation
	* sensorsd(8) and all applicable documentation

	The userland part of the framework is entirely source-code
	compatible with OpenBSD 4.1, 4.2 and  -current as of today.

	All sensor readings can be viewed with `sysctl hw.sensors`,
	monitored in semi-realtime with `systat -sensors` and also
	logged with `sensorsd`.   Third-party tools, for example a
	plug-in for nagios, are also available.  A separate patch
	for ports/sysutils/symon will be provided upon request.

Exact directions on applying and testing:
