synopsis:               Random number generation
description:            Random number generation based on modeling random 
                        variables in two complementary ways: first, by the
                        parameters of standard mathematical distributions and,
                        second, by an abstract type ('RVar') which can be
                        composed and manipulated monadically and sampled in
                        either monadic or \"pure\" styles.
                        .
                        The primary purpose of this library is to support 
                        defining and sampling a wide variety of high quality
                        random variables.  Quality is prioritized over speed,
                        but performance is an important goal too.
                        .
                        In my testing, I have found it capable of speed 
                        comparable to other Haskell libraries, but still
                        a fair bit slower than straight C implementations of 
                        the same algorithms.
                        .
                        Changes in 0.2.4.0: Added a Lift instance that resolves
                        a common overlapping-instance issue in user code.
                        .
                        Changes in 0.2.3.1: Should now build on GHC 7.6
                        .
                        Changes in 0.2.3.0: Added stretched exponential distribution,
                        contributed by Ben Gamari.
                        .
                        Changes in 0.2.2.0: Bug fixes in Data.Random.Distribution.Categorical.
                        .
                        Changes in 0.2.1.1: Changed some one-field data types
                        to newtypes, updated types for GHC 7.4's removal of Eq 
                        and Show from the context of Num, and added RVarT versions
                        of random variables in Data.Random.List

tested-with:            GHC == 7.4.2, GHC == 7.6.1

Flag base4_2
    Description:        base-4.2 has an incompatible change in Data.Fixed (HasResolution)

Flag mtl2
    Description:        mtl-2 has State, etc., as "type" rather than "newtype"
