+#!/usr/bin/env bash
+# This script cleans up local Git branches which have been merged into
+# the main branch.  I use it to clean up the branch view in GitUp
+# (my Git GUI of choice), so I'm not distracted by lots of old branches.
+#
+# It's based on the commands from this Stack Overflow post:
+# https://stackoverflow.com/a/6127884/1558022
