(synopsis "BCJ filter library")
(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 the 7-zip compression utility as the default
filter for executable binaries.
pybcj provides Python bindings to a BCJ implementation in C.")
