# Cache the (saved) docker images.
# With recent version of docker one can reuse a prior image as a
# source cache, that can speed up the builds, as the dependencies and
# images can be reused ...
# TODO() - we need to add a cron job to rebuild without a cache every
# so often, the dependencies do change and we want to validate that
# the examples build with the newer versions.  That is easy to do with
# a cron-based build in Travis that cleans up the cache every X days.
