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

RepLib has been tested with GHC 6.8.3 and 6.10.3.

This library contains the following modules:

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

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

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

RepLib   - Toplevel module that imports 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.
