description:         Easy and reasonably efficient probabilistic programming and random generation
                     .
                     This library gives a common language to speak about
                     probability distributions and
                     random generation, by wrapping both, when necessary,
                     in a 'RandT' monad defined in @Math.Probable.Random@.
                     This module also provides a lot of useful little
                     combinators for easily describing how random values for your
                     types should be generated.
                     .
                     In @Math.Probable.Distribution@, you'll find functions for generating
                     random values that follow any distribution supported by
                     <http://hackage.haskell.org/package/mwc-random mwc-random>.
                     .
                     In @Math.Probable.Distribution.Finite@, you'll find an adaptation
                     of Eric Kidd's work on probability monads (from
                     <http://www.randomhacks.net/probability-monads/ here>).
                     .
                     You may want to check the examples bundled with this package,
                     viewable online at <https://github.com/alpmestan/probable/tree/master/examples>.
                     One of these examples is simple enough to be worth reproducing here.
