DESCRIPTION
This library may be used to automatically generate free theorems
[1,2] from Haskell type signatures. It supports Haskell 98 and
additionally higher-rank functions. Beside primitive Haskell types
(Int, Integer, Float, Double, Char), it already includes lists and
tuples. The library provides means to add other data types.
DEPENDENCIES
See the file `free-theorems.cabal' for dependencies. Note that there,
two parser libraries are listed. If only one is needed, the library
is easily adjustable by commenting out the corresponding dependencies
and exported modules.
INSTALL
Since this library is cabalised, it uses the standard installation
process.
runhaskell Setup.lhs configure
runhaskell Setup.lhs build
runhaskell Setup.lhs install
USAGE
See the Haddock-generated documentation for detailed information on
how to use this library.
DOCUMENTATION
If Haddock is available, documentation may be
generated automatically from the sources.
