This project was first conceived to manipulate Apple’s software restore packages (IPSWs) and hence much of it is geared specifically toward that format. Useful tools to read and manipulate the internal data structures of those files have been created to that end, and with minor changes, more generality can be achieved in the general utility. An inexhaustive list of such changes would be selectively enabling folder counts in HFS+, switching between case sensitivity and non-sensitivity, and more fine-grained control over the layout of created dmgs. Extensive testing have not been done, but comparatively simple tasks like adding and removing files from a mostly contiguous filesystem are well proven. Please note that these tools and routines are currently only suitable to be accessed by other programs that know what they’re doing. I.e., doing something you "shouldn’t" be able to do, like removing non-existent files is probably not a very good idea.
