+This job takes care of publishing snapshots for primary branches.

+It is triggered automatically on push to each branch, but throttled
+to avoid problems when multiple PRs get merged in short span of time.
+
+See [ci/snapshot-publish/Jenkinsfile](ci/snapshot-publish/Jenkinsfile) for the job definition.
