# This script is a wrapper to use pbuilder with many different
# distributions / versions.
#
# If you want to use this copy of the script only for a single distribution
# / version, rename it to 'pbuilder-dapper', 'pbuilder-feisty', 'pbuilder-gutsy', 
# or whatever it is. If you have an amd64, you can also use names like
# 'pbuilder-feisty-i386', etc.
#
# The only variable you really might need to change is BASE_DIR, if you
# don't want pbuilder stuff in your home directory.
