+      ''  Brotli is a generic-purpose lossless compression algorithm that
+          compresses data using a combination of a modern variant of the LZ77
+          algorithm, Huffman coding and 2nd order context modeling, with a
+          compression ratio comparable to the best currently available
+          general-purpose compression methods. It is similar in speed with
+          deflate but offers more dense compression.
+
+          The specification of the Brotli Compressed Data Format is defined
+          in the following internet draft:
+          http://www.ietf.org/id/draft-alakuijala-brotli
