A great feature would be, if an 'urlcheck' program does not only check the
validity of links but does also help keeping the links valid. It could
download copies of each referenced HTML document as long as the links are
valid. If on a check run a link is unreachable it could ask a search
engine for an alternative copy with the same content. That's certainly
easier said than implemented.
