(synopsis "Random number generation library for Haskell")
(description "This Haskell package contains code for generating
high quality random numbers that follow either a uniform or normal
distribution. The generated numbers are suitable for use in
statistical applications.
The uniform PRNG uses Marsaglia's MWC256 (also known as MWC8222)
multiply-with-carry generator, which has a period of 2^{8222} and
fares well in tests of randomness. It is also extremely fast,
between 2 and 3 times faster than the Mersenne Twister.")
