Introduction
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.
Brotli is open-sourced under the MIT License, see the LICENSE file.

Build instructions
Autotools-style CMake
configure-cmake is an autotools-style configure script for CMake-based projects.
The basic commands to build, test and install brotli are:
$ mkdir out && cd out
$ ../configure-cmake
$ make
$ make test
$ make install
To build static libraries use --disable-shared-libs
argument:
$ mkdir out-static && cd out-static
$ ../configure-cmake --disable-shared-libs
$ make install
Bazel
See Bazel
CMake
The basic commands to build, test and install brotli are:
$ mkdir out && cd out
$ cmake ..
$ make
$ make test
$ make install
You can use other CMake configuration. For example, to build static libraries:
$ mkdir out-static && cd out-static
$ cmake .. -DBUILD_SHARED_LIBS=OFF
$ make
Premake5
See Premake5
Python
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.
