Zopfli Compression Algorithm is a compression library programmed in C
to perform very good, but slow, deflate or zlib compression.

The basic function to compress data is ZopfliCompress in zopfli.h. Use
the ZopfliOptions object to set parameters that affect the speed and
compression. Use the ZopfliInitOptions function to place the default
values in the ZopfliOptions first.

ZopfliCompress supports deflate, gzip and zlib output format with a
parameter. To support only one individual format, you can instead use
ZopfliDeflate in deflate.h, ZopfliZlibCompress in zlib_container.h or
ZopfliGzipCompress in gzip_container.h.

This library can only compress, not decompress. Existing zlib or
deflate libraries can decompress the data.

Zopfli Compression Algorithm was created by Lode Vandevenne and Jyrki
Alakuijala, based on an algorithm by Jyrki Alakuijala.
