Version : 1.0.9
Release : 3.fc33
URL :   https://github.com/google/brotli
Summary : Lossless compression algorithm
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.
