:trivial: adj. 1. Too simple to bother detailing. 2. Not worth the
speaker's time. 3. Complex, but solvable by methods so well known
that anyone not utterly {cretinous} would have thought of them
already. 4. Any problem one has already solved (some claim that
hackish `trivial' usually evaluates to `I've seen it before').
Hackers' notions of triviality may be quite at variance with those
of non-hackers. See {nontrivial}, {uninteresting}.
