%description
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.

pybcj is a python bindings with BCJ implementation by C language. The C codes are
derived from p7zip, portable 7-zip implementation. pybcj support Intel/Amd
x86/x86_64, Arm/Arm64, ArmThumb, Sparc, PPC, and IA64.
