+%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).
