# This script checks if container images needed for tests (currently
# busybox and Debian 10 "Buster") are available locally, and downloads
# them to testdata directory if not.
#
# The script is self-contained/standalone and is used from a few places
# that need to ensure the images are downloaded. Its output is suitable
# for consumption by shell via eval (see helpers.bash).
