# The Lazy Guy's packaging tool for gBootRoot.
# This program sets-up the archive which will be turned into a package and 
# needs to be run as root.  The advantage of this program is that the 
# archive will always represent the Makefile which is being tested
# when development isn't being done with perl -I . ./gbootroot.

# This program uses dh-make, and copies your own defaults to 
# $packaging_place/debian from your $packaging_defaults, and updates
# to the proper date/times.
