(synopsis "Extremely fast hash algorithm")
(description
"xxHash is an extremely fast non-cryptographic hash algorithm. It works
at speeds close to RAM limits, and comes in both 32- and 64-bit flavours.
The code is highly portable, and hashes of the same length are identical on all
platforms (both big and little endian).")
