# script/docker: build the Docker image tagged with the project name.
# Identical in all repos; the tag comes from script/projectname.
# Generic: needs no adaptation.
#
# This builds the PRODUCT image only, and the product Dockerfile has no
# lint stage: linting lives in Dockerfile.lint and is run by
# script/lint. So a green here means `make fmt-check` and `make test`
# passed and the image built -- it says nothing about lint. The gates
# are script/check (which runs script/lint) and script/cibuild (which
# builds both files).

    # without a non-empty value, so this is required, not optional.
