+description         High performance block-sorting data compressor
+long_description    ${name} is a high performance file compressor based on lossless, block-sorting data\
+                    compression algorithms. lib${name} is a library based on ${name}, it uses the same\
+                    algorithms as ${name} and enables you to compress memory blocks.
