# netpage.alert - network page alert for mon
#
# The first line from STDIN is summary information, adequate to send
# to a pager or email subject line. Even though this code is entirely
# trivial, I wrote it just so that when it's specified in the mon.cf
# file, it is clear that the paging alert is network-dependent.
