        In data compression, BCJ, short for Branch-Call-Jump, refers to a technique that improves the compression of
        machine code of executable binaries by replacing relative branch addresses with absolute ones.
        This allows a LZMA compressor to identify duplicate targets and archive higher compression rate.
        
        BCJ is used in 7-zip compression utility as default filter for executable binaries.
        
        bcj-cffi is a python bindings with BCJ implementation by C language.
        The C codes are derived from p7zip, portable 7-zip implementation.
        bcj-cffi support Intel/Amd x86/x86_64, Arm/Arm64, ArmThumb, Sparc, PPC, and IA64.
