+# This is an old script that doesn't necessarily work very well with
+# today's sources. If anyone wants to fix it up, it might be worth the
+# effort, as it could help catch some mistakes that we have overlooked.
+#
+# If you want to work on this, consider fundamentally rethinking the
+# approach. Instead of flagging anything that *might* be an error,
+# maybe it should flag only things that we are *sure* are an error.
+# That would make it possible to run this as a matter of routine, just
+# as we already do with codespell (see "admin/run-codespell").
