# Decide on the versionid policy.
#
# If the user has passed in $(VERSION) on the command line (`make
# VERSION="Release 0.56"'), we use that as an explicit version string.
# Otherwise, we use `svnversion' to examine the checked-out
# documentation source, and if that returns a single revision number
# then we invent a version string reflecting just that number. Failing
# _that_, we resort to versionids.but which gives 'version
# unavailable'.
#
# So here, we define VERSION using svnversion if it isn't already
# defined ...
