-# to alarm if a domain is about to expire.
-#
-# License:
-# This program is distributed in the hope that it will be useful,
-# but WITHOUT ANY WARRANTY; without even the implied warranty of
-# MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
-#
-# Notes:
-# Since each registrar provides expiration data in a unique format (if
-# they provide it at all), domain-check is currently only able to
-# processess expiration information for a subset of the available
-# registrars.
-#
-# Requirements:
-# Requires whois
-#
-# Installation:
-# Copy the shell script to a suitable location
-#
-# Tested platforms:
-# -- Solaris 9 using /bin/bash
-# -- Solaris 10 using /bin/bash
-# -- OS X 10.4.2 using /bin/sh
-# -- OpenBSD using /bin/sh
-# -- FreeBSD using /bin/sh
-# -- Redhat advanced server 3.0MU3 using /bin/sh
-#
-# Usage:
-# Refer to the usage() sub-routine, or invoke domain-check
-# with the "-h" option.
-#
-# Example:
-#
-# The first example will print the expiration date and registrar for prefetch.net:
-#
-# $ domain-check.sh -d prefetch.net
-#
-# Domain Registrar Status Expires Days Left
-# ----------------------------------- ----------------- -------- ----------- ---------
-# prefetch.net INTERCOSMOS MEDIA Valid 13-feb-2006 64
-#
-# The second example prints the expiration date and registrar for the domains
-# listed in the file "domains":
-#
-# $ domain-check.sh -f domains
-#
-# Domain Registrar Status Expires Days Left
-# ----------------------------------- ----------------- -------- ----------- ---------
-# sun.com NETWORK SOLUTIONS Valid 20-mar-2010 1560
-# google.com EMARKMONITOR INC. Valid 14-sep-2011 2103
-# ack.com NETWORK SOLUTIONS Valid 09-may-2008 880
-# prefetch.net INTERCOSMOS MEDIA Valid 13-feb-2006 64
-# spotch.com GANDI Valid 03-dec-2006 357
-#
-# The third example will e-mail the address admin@prefetch.net with the domains that
-# will expire in 60-days or less:
-#
-# $ domain-check -a -f domains -q -x 60 -e admin@prefetch.net
-#
-
-PATH=/bin:/usr/bin:/usr/local/bin:/usr/local/ssl/bin:/usr/sfw/bin ; export PATH
-
-# Who to page when an expired domain is detected (cmdline: -e)
-ADMIN="root"
-
-# Number of days in the warning threshhold (cmdline: -x)
-WARNDAYS=30
-
-# If QUIET is set to TRUE, don't print anything on the console (cmdline: -q)
-QUIET="FALSE"
-
-# Don't send emails by default (cmdline: -a)
-ALARM="FALSE"
-
-# Whois server to use (cmdline: -s)
-WHOIS_SERVER="whois.internic.org"
-
-# Location of system binaries
-AWK="/usr/bin/awk"
