+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."
