-- RepLib 
--    a library of derivable type classes based on representation types
--  See for more information.

RepLib has been tested with GHC 7.0.1.  It currently does not compile with 
GHC 6.12.x or earlier.

This library contains the following modules:

Generics.RepLib.R           - Basic type representations
Generics.RepLib.R1          - Parameterized type representations
Generics.RepLib.Derive      - Template Haskell code to automatically derive 
                              representations of datatypes.
Generics.RepLib.PreludeReps - Reps of Prelude types
Generics.RepLib.RepAux      - Helper functions to define type-indexed functions

Generics.RepLib.Lib         - Examples of specializable type-indexed functions
Generics.RepLib.PreludeLib  - Examples type-indexed functions from prelude

Generics.RepLib.SYB.Aliases - SYB: Port of Data.Generics.Aliases
Generics.RepLib.SYB.Schemes - SYB: Port of Data.Generics.Schemes

RepLib                      - Top-level module that re-exports all of the above

To use this library, import RepLib and derive representations of your
datatypes. The "Lib" module contains a number of type-indexed
operations that have been predefined.  To see an example of
automatically deriving the representation of a datatype, see the file

Currently, the representations of datatypes with record components,
GADTs and nested datatypes cannot be automatically derived.
