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.

To build and run tests, simply do:
$ ./configure && make
If you want to install brotli, use one of the more advanced build systems below.
The basic commands to build, test and install brotli are:
$ mkdir out && cd out && ../configure-cmake && make $ make test $ make install
You can use other CMake configuration. For example, to build static libraries and use a custom installation directory:
$ mkdir out-static && \ cd out-static && \ ../configure-cmake --disable-shared-libs --prefix='/my/prefix/dir/' $ make install
To install the Python module from source, run the following:
$ python setup.py install
See the Python readme for more details on testing and development.
