#
#   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.
