+%description
+Pure Haskell implementation of SplitMix described in
+
+Guy L. Steele, Jr., Doug Lea, and Christine H. Flood. 2014. Fast splittable
+pseudorandom number generators. In Proceedings of the 2014 ACM International
+Conference on Object Oriented Programming Systems Languages & Applications
+(OOPSLA '14). ACM, New York, NY, USA, 453-472. DOI:
+<https://doi.org/10.1145/2660193.2660195>
+
+The paper describes a new algorithm /SplitMix/ for /splittable/ pseudorandom
+number generator that is quite fast: 9 64 bit arithmetic/logical operations per
+64 bits generated.
+
+/SplitMix/ is tested with two standard statistical test suites (DieHarder and
+TestU01, this implementation only using the former) and it appears to be
+adequate for "everyday" use, such as Monte Carlo algorithms and randomized data
+structures where speed is important.
+
+In particular, it __should not be used for cryptographic or security
+applications__, because generated sequences of pseudorandom values are too
+predictable (the mixing functions are easily inverted, and two successive
+outputs suffice to reconstruct the internal state).
