# Script to get SVN HEAD and make a .tar.gz on a shared disk, for use by
# autobuild scripts on our build machines.
#
# Should be run on the SVN server (or some other system that can access SVN
# readonly without a password) from a crontab, e.g.
#
# 10 1 * * * /cowbell1/home/ben/imp/tools/auto-build.sh
#
# In this case, the build user is in the apache group, and so has readonly
# access to the repositories.
