+SUMMARY="A stateless, zlib-compatible, and very fast compression library"
+DESCRIPTION="SLZ is a fast and memory-less stream compressor which produces an \
+output that can be decompressed with zlib or gzip. It does not implement \
+decompression at all, zlib is perfectly fine for this.
+
+The purpose is to use SLZ in situations where a zlib-compatible stream is \
+needed and zlib's resource usage would be too high while the compression ratio \
+is not critical. The typical use case is in HTTP servers and gateways which \
+have to compress many streams in parallel with little CPU resources to assign \
+to this task, and without having to thottle the compression ratio due to the \
+memory usage. In such an environment, the server's memory usage can easily be \
+divided by 10 and the CPU usage by 3. In addition its high performance made it \
+fill a gap in network backup applications."
