+ (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.")
