# This scripts re-tags images from one branch to another. Since we keep
# images "per-branch" we sometimes need to "clone" the current
# images to provide a starting cache image to build images in the
# new branch. This can be useful in a few situations:
#
# * when starting new release branch (for example `v2-1-test`)
# * when renaming a branch
