# for getting data from the user and returning it back to us. Our default 
# is rather simple, but if a packager wishes to use a Tk front-end or customize 
# the look and feel of the installation process to match with their system, they 
# can override our controller by making a new one and setting 
# $Conf::controller = "foo" in a custom Configure.pl
# This is really intended for debian-style configuration systems
