качаешь исходники\устанавливаешь xdelta-1.1.3 имеем, к примеру arts-1.5.4.tar.bz2 и arts-1.5.4-1.5.5.tar.xdelta делаем: 1. bunzip2 arts-1.5.5.tar.bz2 2. xdelta patch arts-1.5.4.tar arts-1.5.4-1.5.5.tar.xdelta получаем на выходе arts-1.5.5.tar 3. bzip2 -9 arts-1.5.5.tar ну и так со всеми файлами

проще говоря - это патчи на tar-файлы

Thanks.
