# Log4OM sends it's packets every five seconds. So we wait six to see if a packet comes in.
# If it does, we parse the XML and send it as arguments to writehtml()
#
# If it doesn't....
#
# Then we create the sleepy variable by subtracting tot from time.time(). If it's more than
# a minute; we run checkrig(). If it's not, we go away. After a minute has passed, we check
# again and reset the counter.
#
# This largely is done so we can daemon the script and have it pick back up when things change.
#
# You also probably shouldn't modify anything here unless you know what you're doing.
