#
# DESCRIPTION:
#   A shell script to be called from MBProbe <http://mbprobe.livewiredev.com/>
#   when measurements go into the Critical zone.  Quickly and unceremoniously
#   shuts down the machine.
#
#   MBProbe has a builtin Shutdown feature, but on most machines it only shuts
#   down to the "It is now safe to shutdown your computer" screen rather than
#   powering off.  Note that if you set "On Critical" to "Do nothing", this 
#   script will not be called (up through MBProbe 1.31 Beta 9, at least), even
#   if you have a check box by Critical's "Execute Program".  If you set "On
#   Critical" to Shutdown, the incomplete shutdown will generally finish before 
#   this script finishes doing a complete one.  Therefore, you must use the 
#   "Suspend" setting, which luckily fails to actually suspend most machines, 
#   and this script will be successfully called.
#
#   This script requires Cygwin <http://sources.redhat.com/cygwin/>.  You must 
#   associate the .sh extension with the bash.exe or sh.exe executables, and of
#   course have your <drive>:\cygwin\bin directory in the system's PATH (for the
#   necessary DLL(s)).  After you do associate it, be careful not to double-
#   click on this file, or you will, of course, shut down your machine.  If you
#   do the associating using Open With in Windows Explorer, the same thing will
#   happen (you may find this a useful confirmation that the script works, but
#   be prepared for it).
#
# DATE        MODIFICATION
# ==========  ==================================================================
# 2005-09-27  As of Cygwin shutdown 1.7-1 (2005-04-23), we need to use -x (which
#             uses ExitWindowsEx() rather than InitiateSystemShutdown()) on
#             Windows 2000 to power all the way down rather than just going to
#             the "It is now safe..." screen.  For more info, see 
#             www.mail-archive.com/cygwin-announce@cygwin.com/msg01150.html.
# 2002-12-14  On current version of Cygwin, need to set PATH explicitly.
# 2002-08-19  Original.
