alternative prelude with batteries and no dependencies; profiling libraries

A custom prelude with no dependencies apart from base.

This package has the following goals:

 * provide a base like sets of modules that provide a consistent set
   of features and bugfixes across multiple versions of GHC (unlike base).
 * provide a better and more efficient prelude than base's prelude.
 * be self-sufficient: no external dependencies apart from base.
 * provide better data-types: packed unicode string by default, arrays.
 * Better numerical classes that better represent mathematical thing
   (No more all-in-one Num).
 * Better I/O system with less Lazy IO
 * Usual partial functions distinguished through type system

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