I might mind, but I don't think I'd be able to give any good
reason why.  I think it's kinda neat to look through an old
manual from time to time.

Well, the problem with "archive" is that the latest
development docs would be there too, because we shouldn't
let google track those either.  "Archive" implies old, and
the dev docs are new.
