+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 @code{deflate} but offers more dense compression.
+
+The specification of the Brotli Compressed Data Format is defined in RFC 7932.")
