...or Zig's Mach-O parser. This project started off as a dummy scratchpad for reinforcing my understanding of the Mach-O file format while I was working on the Zig's stage2 Mach-O linker (I still am working on it, in case anyone was asking).
My current vision for zacho is for it to be a cross-platform version of otool and pagestuff
macOS utilities. These seem to be very useful when battling the Darwin kernel and dyld when those
refuse to load your hand-crafter binary, or you just like looking at Mach-O dissected output.
Usage: zacho [options] file
