I am trying to read and write the PMSP file produced by PackageMaker. Looking into it, you can see it is a binary file and somewhere close to the beginning is a string: typedstream. I found some information about typedstream, but the most promising is the code in GNU Objective C. That said, before I go and rip a bunch of code out of gcc, is there any simple explanation on the PMSP file format? I figured out all strings have length prepended, but there is much more that is changing. Also, (question for the apple guys) is there a problem with reverse engineering pmsp file? Will it change anytime soon? This email sent to site_archiver@lists.apple.com
