I take that back. This patch suffers from the same problem as an earlier
version of mine: As soon as there is a change to one of the scripts, the
'reference' file will be regenerated on every make invocation, which
takes some time (split second, but still noticeable). That's why I added
the persistent .tmp file in the version I sent.
