    (synopsis "General-purpose lossless compression")
    (description "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 RFC 7932.")
