+ "A portable library of functor and monad transformers, inspired by the
paper
+'Functional Programming with Overloading and Higher-Order Polymorphism',
+by Mark P Jones. This package contains the monad transformer class and IO
monad class,
+concrete functor and monad transformers, each with associated operations and
functions
+to lift operations associated with other transformers. The package can be
used on
+its own in portable Haskell code, in which case operations need to be manually
lifted
+through transformer stacks. Alternatively, it can be used with the
+non-portable monad classes in the @code{mtl} or @code{monads-tf} packages,
+which automatically lift operations introduced by monad transformers through
+other transformers.")
