# Script to automate backporting r-base for CRAN
# Author: Johannes Ranke <jranke@uni-bremen.de>
# Developed in parallel with Vincent Goulet <vincent.goulet@act.ulaval.ca>
# On Debian I used to run this script as root. On Ubuntu I now run it with
# sudo -E sh backport_r-base.sh
# Preconditions: - shell variables DIST and ARCH
# - sid sources in /etc/apt/sources/list
# - cdbs installed (and maybe more)
