 Control.Monad.Trans.Resource allocates resources which are guaranteed
 to be released. One point to note: all register cleanup actions live
 in the IO monad, not the main monad. This allows both more efficient
 code, and for monads to be transformed.

 This package provides the documentation for a library for the Haskell
 programming language.
