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