+     "This package provides a Pure Haskell implementation of the
+SplitMix pseudorandom number generator.  SplitMix is a \"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 @strong{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).")
