#
# The registry generates the hookPayload that appears in actions.json, and
# contains data from the decision task as well as JSON-e code to combine that
# with data supplied as part of the action spec. When the hook is fired, the
# hookPayload is rendered with JSON-e to produce a payload for the hook task
# template.
#
# The ci-admin code wraps the content of this file (.taskcluster.yml) with a
# JSON-e $let statement that produces the context described below, and
# installs that as the hook task template.
