Exploite Stuffit Engine
I have finished porting the version 4 SDK for the Stuffit Engine into a DCOD. You can now do self-extracting archives, handle .bin, .hqx, .zip, uu, .tar, and everything else that Stuffit does. I have also built-in a bug fix for the the memory leak in the engine, which you can turn on or off (It might cause problems?).
And no, it won't do segmenting or archive walking (Unless you have some spare money hanging around to pay me for a months work... :->)
