# macro for building an image by targeting a Docker image stage

# I expect variant Docker images to use staged image specifications, that share
# a base image.  In the case of the ``build`` docker image, which provides build
# environments, there are versioned runtime environment variants, e.g.
# ``python39``, ``node19``, that all share a ``build`` base, resulting in full
# image tag names such as ``build-python39`` and ``build-node19``.
