Transformers for Reader and State Monoids; documentation

 This library provides Monoid Transformers for the Reader Monoid and
 the State Monoid. There's no Monoid Transformer for the Writer Monoid
 since the Writer Monad transforms a Monoid into a Monad.
 This package provides the documentation for a library for the Haskell
 programming language.
 See http://www.haskell.org/ for more information on Haskell.
