# This script is an interactive wrapper around the scripts build.sh, tag.sh
# and push.sh intended for use during official Terraform releases.
#
# This script should be used only when git HEAD is pointing at the release tag
# for what will become the new latest *stable* release, since it will update
# the "latest", "light", and "full" tags to refer to what was built.
#
# To release a specific version without updating the various symbolic tags,
# use build.sh directly and then manually push the single release tag it
# creates. This is appropriate both when publishing a beta version and if,
# for some reason, it's necessary to (re-)publish and older version.
