This is a simple solver for quantifier-free linear integer arithmetic. It uses Cooper's algorithm and is written in Haskell. To build and install, use cabal in the root of the repository working directory:
$ cabal build
$ cabal install
The test suite runs randomly-generated instances against Iavor S. Diatchki's solver (imported through cabal) which uses a different algorithm:
$ cabal test
The tests may take a few minutes to run if the instances generated are difficult.
