+Zopfli Compression Algorithm is a compression library programmed in C to perform
+very good, but slow, deflate or zlib compression.
+
+gzip.c is separate from the library and contains an example program to create
+very well compressed gzip files.
+
+The basic function to compress data is Deflate in deflate.h. Use the Options
+object to set parameters that affect the speed and compression. Use the
+InitOptions function to place the default values in the Options first.
+
+This function creates a valid deflate stream. To get a valid zlib stream
+instead, you need to add a small zlib header and a checksum around this stream
+yourself. Please see the Zlib specification for more details:
+http://www.ietf.org/rfc/rfc1950.txt.
+
+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.
