HWUN is an heuristic WISE-Setup Unpacker, intended to break the bindings to static version tables of WISE as EXWISE (Andrew de Quincey) and E_WISE (Veit Kanngieser) do. The advantage is that HWUN could handle future WISE versions, too, without any further update. The disadvantage is, that the heuristic methods may not work on several types which EXWISE orE_WISE would unpack successfully.
