  49           Compression parameters should only be tuned by someone who understands
  50           the algorithm used by zlib's deflate for searching for the best matching
  51           string, and even then only by the most fanatic optimizer trying to squeeze
  52           out the last compressed bit for their specific input data. Read the deflate.c
  53           source code (ZLib) for the meaning of the max_lazy, good_length, nice_length,
  54           and max_chain parameters.
