  56     (description
  57      "xxHash is an extremely fast non-cryptographic hash algorithm.  It works
  58 at speeds close to RAM limits, and comes in both 32- and 64-bit flavours.
  59 The code is highly portable, and hashes of the same length are identical on all
  60 platforms (both big and little endian).")
