This is a crucial tool for anyone looking to merge a base game with its updates into a single, smaller package. The tool by Duxa (Chrushev) is a community standard for this process. It works by taking a base game .pkg and a patch .pkg and combining them. The tool intelligently replaces old files with newer ones from the patch, resulting in a single repackaged .pkg that is smaller than the sum of its parts [7†L3-L6] [9†L8-L19].
