The only practical ones would be the FreeBSD advisories; they're the
only ones which relate to the FreeBSD Ports Collection directly.

I'd prefer not to have to maintain a separate database, because
history tells us that it will become stale.

We've talked about sticking them in the CVS repo, but they're not
currently there (besides, most people don't cvsup the www collection,
where they'd probably live).  The FTP site is the only canonical
