Prawie działający CLodHandler - z moich testów wynika, że ma tylko problemy z wydajnością (nie wiem, ile tu można zrobić, być może i dużo) oraz z obrazkami (coś dziwnego z nimi zrobiono...). Wszystko powinno dobrze działać (pamiętaj o dostarczeniu odpowiednich plików i stworzenie folderów: po jednym dla każdego rozpakowywanego loda, o nazwie będącej nazwą tego loda bez rozszerzenia, plus jeden dodatkowy dla rozpakowywacza o nazwie lodbuf)
