#!/usr/bin/env sh
# Protect the release lines, for the projects that keep older lines: while a
# line is alive, release/* can be neither force-pushed nor deleted. Direct
# pushes stay allowed, because a cherry-pick lands on a line by push. This
# step is optional — a project with no older lines never runs it — and when a
# line dies its tags pin the commits, so the operator removes this ruleset
# together with the last line. Rerunning updates in place.
