28 xxHash is an Extremely fast Hash algorithm, running at RAM speed limits.
29 It successfully completes the SMHasher test suite which evaluates
30 collision, dispersion and randomness qualities of hash functions. Code is
31 highly portable, and hashes are identical on all platforms (little / big
32 endian).
