# This module needs to include a conf-<configtype>.pl 
# module that defineds two subroutines.  On called 'setup'
# that calls setups up the interface to that module and
# another called 'lookup_value' that returns a value for
# a given Lookup,Property pair.
#
# Be sure to also look at the conf-csv.pl/conf-mysql.pl
# in the lib directory for setup instructions.
#
# The following table shows what Lookup values are used for a
# given Property value.  The order shown is the order searched.
# The search ends when a valid entry is returned with the 
# exception of UnattendedFile.  UnattendedFile will search and
# apply all files in order listed.  Default is sort of redundant
# for UnattendedFile as z:\site\unattend.txt is considered Default.
