The Coverty people keep saying they will be getting back to me soon as
to how they can run this for us in a way that is useful (they know the
false positives are horrible and make it useless).  But I haven't heard
back from them in a few weeks now, so I don't know what's up with it.

So, supposidly someone is working on this, and as it's closed source,
there's not much any of us can do to help out :(
