standard library for Haskell; profiling libraries

 The goal of the rio library is to make it easier to adopt Haskell for writing
 production software. It is intended as a cross between:
  * Collection of well designed, trusted libraries
  * Useful Prelude replacement
  * A set of best practices for writing production quality Haskell code
 .
 This package provides a library for the Haskell programming language, compiled
 for profiling. See http://www.haskell.org/ for more information on Haskell.
