-      Template for projects requiring updates to their
-      docs-on-readthedocs usage.  Because project managers
-      are required to update their project, infra can not
-      fix deployment.  Since rtd triggering only
-      happens in the post pipeline, nobody really checks the
-      results of the jobs.  Not everyone reads the mailing list as
-      closely as we might like.  The result is a lot of projects
-      with broken documentation publishing that don't know about it.

-      This job always fails and provides a link to the mailing list
-      post with details of how to fix the job.
