+# This script was developed for use in Moby's CI, and as such the use cases and
+# usability are (intentionally) limited. You may find this script useful for
+# educational purposes, for example, to learn how pulling images works "under
+# the hood", and you may be able to use it for other purposes, but it should not
+# be considered a "general purpose" tool for pulling images.

+# The project maintainers accept contributions to this script within its intended

+# For users who have a similar need but require more flexibility/functionality,
+# refer the the discussion on GitHub, which mentions various alternatives that
+# are more suitable for other uses: https://github.com/moby/moby/issues/40857
