#!/usr/bin/awk -f
#
# Author: Matt Pascoe - matt@opennetadmin.com
#
# This awk script is used to extract relavant information from a dhcpd.conf
# config file and build dcm.pl output with appropriate fields.  This can be
# used to bootstrap a new database from existing site data.
# As usual, inspect the output for accuracy.
# Also you will get three types of output, subnet,pool,host.  You must
# add the subnet information first, then pool, then host.
