# This workflow builds and pushes a new version of the build container image
# when the tools directory changes on master. Edit tools/Dockerfile.
#
# This workflow does not push a new image until it is merged, so tests that
# depend on changes in this image will not pass until this workflow succeeds.
# For that reason, changes here should be done in a separate PR in advance of
# work that depends on them.
