# /usr/local/mouseup RM200702018
#     A script that tests for user activity based on mouse activity 
# shuts down if given programs are not running and there has been no  
# mouse activity for declared period of time. Mouse activity is based 
# on a comparison of output of the mouse device as listed in the table 
# /proc/interrupts.
#    You would have to check /proc/interrupts and determine which line
# number belongs to your mouse. On the box this script runs on, there 
# are two interupt entries "i8402". Probably every mobo I've had shares 
# IRQ's so this is not unusual. I determined that the one on line 12
# belonged to the mouse (the other is the keyboard) and edited so that 
# variable INTRPT_LINE=12.
#    This script creates a log file /var/log/mouseup which is overwritten 
# by the first new log entry made by mouseup $INTRPT_LINE after a boot.  
#    I run this script at boot by putting the following line in 
# /etc/rc.d/rc.local: "/usr/local/bin/mouseup 45 > /dev/null 2>&1 $". The
# the number following the command sets the period of time between checks.
