# A previous iteration of calculating "LATEST_RELEASED_SEMCONV_VERSION"
# relied on "git describe". However, that approach does not work with
# light-weight developer forks/branches that haven't synced tags. Hence the

#
# The output of "git ls-remote" looks something like this:
#
#    e531541025992b68177a68b87628c5dc75c4f7d9        refs/tags/v1.21.0

#    ...
#
# .. which is why some additional processing is required to extract the
# latest version number and strip off the "v" prefix.
