I know, I know. And I really don't mind removing link from website :)
Your're right; JtR's main site shouldn't be hosting every, err,
experiment. If someone need it, he'll find it... or write by himself.

Well, maybe I will ;) Really, I though that this *something* is so
specific, that any generalization would be just a redundant overhead.

Because I was mentioning about salted domino patch optimization :>
Little inconsistency as I was also referring to single/incremental
discussion.

I'd love to! Any hints? :)

I see. So what for this ./configure-like thingie would be used?
