# Preconditions: - shell variables DIST and ARCH
#                - current R backport in /etc/apt/sources/list of pbuilder chroot
#                - sid sources in /etc/apt/sources/list
#                - ssed and cdbs installed (and maybe more)
#                - Edit R version and the sed scripts below (don't forget
#                  distribution name) to the appropriate version of R
#                - Set the R version

# R version against which the software is compiled
Rversion=3.0.0
