+  summary: Extremely fast hash algorithm
+  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).
