+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).
