# Usage: counterlog [annotation]

# Syslog a message at user.notice (which goes to wslogger.mit.edu in
# the normal Athena configuration) containing the hostname, machtype,
# cputype, Athena version, system identifier, and the annotation if
# specified.

# The system identifier is a random number chosen the first time this
# script runs.  It is intended to help distinguish machines which
# change IP addresses due to DHCP.

# This script is run from the Athena boot script and from a root cron
# job.

# If you don't want this logging to happen, touch
# /etc/athena/no-counterlog.
