#
# healthd -- This is a simple daemon which can be used to alert you in the
# event of a hardware health monitoring alarm by sending an
# email to the value of ADMIN_EMAIL (defined below).
#
# To Use -- Simply start the daemon from a shell (may be backgrounded)
#
# Other details -- Checks status every 15 seconds. Sends warning emails every
# ten minutes during alarm until the alarm is cleared.
# It won't start up if there is a pending alarm on startup.
# Very low loading on the machine (sleeps almost all the time).
# This is just an example. It works, but hopefully we can
# get something better written. :')
#
# Requirements -- mail, sensors, bash, sleep
#
