SUMMARY="Optimal LZ77/LZSS data compressor"
DESCRIPTION="Available implementations of standard LZ77/LZSS compression \
algorithm use either a greedy or flexible parsing strategy, that cannot always \
guarantee the best possible encoding. In comparison, ZX7 provides a highly \
efficient compression algorithm that always generate perfectly optimal \
LZ77/LZSS encoding. Technically it means compressing within space and time \
O(n) only."
