+#
+# Add support for a newer version of an Operating System if the previous
+# version is supported.  Update metadata.json, create a feature branch, commit,
+# and open a PR automatically.
+# If the previous version was not supported but older version are, prompt the
+# user interactively for what to do.
+# If the OS is not supported at all, do nothing.
+#
+# Typical usage (when Debian 13 is released):
+#
+#     bundle exec msync execute -B -- git pull
+#     bundle exec msync execute -B -- $PWD/bin/add-support-for-new-os -o Debian -v 13
