# This script is a wrapper to use pbuilder with many different
# distributions / versions. (It was originally created because of
# bug #255165 in Debian.)
#
# 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.

# Base directory where pbuilder will put all the files it creates
BASE_DIR="$HOME/pbuilder"

# Enable additional repositories by default? (universe and multiverse in Ubuntu,
# contrib and non-free in Debian.)
EXTRACOMP=1

# Save the log of the last operation in a dot-file? ('.lastlog' in BASE_DIR)
SAVELOG=0

# Allow this script to use /var/cache/apt/archives/ when possible
