#
# Used to test 'podman build' functionality "by hand"
# until we're able to install Buildah in the Travis CI
# test system.
#
# Requires podman and Buildah to be installed on the
# system.  This needs to be run from the libpod
# directory after cloning the libpod repo.
#
# To run:
#   /bin/bash -v test_podman_build.sh
