random number generation; profiling libraries

 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.
 .
 This package provides a library for the Haskell programming language, compiled
 for profiling. See http://www.haskell.org/ for more information on Haskell.
