# The rest is probably going to change... The mv below is for backwards

# ln -s nagios-plugins-${VS#release-}.tar.gz nagios-plugins-$HEAD.tar.gz
# ln -s nagios-plugins-${VS#release-}.tar.gz nagios-plugins-trunk-$DS.tar.gz
# ln -s nagios-plugins-master.tar.gz nagios-plugins-HEAD.tar.gz
# NB: the 3rd one would be permannent, no need to do it each time
# Additionally, we could check whenever we need to re-generate a snapshot.
# This way we could make snapshots much more often as only symlink changes
# would have to be uploaded.
mv nagios-plugins-${VS#release-}.tar.gz nagios-plugins-trunk-$DS.tar.gz
