This is twee, an equational theorem prover.

The version in this git repository is likely to be unstable!
To install the latest stable version, run:

    cabal install twee

If you have LLVM installed, you can get a slightly faster version by
running:

    cabal install twee -fllvm

If you really want the latest unstable version, run
`cabal install src/ .` in this repository. You will most likely need
the latest git version of Jukebox, from
https://github.com/nick8325/jukebox, too - and things may break from
time to time.

Afterwards, run `twee nameofproblem.p`. The problem should be in TPTP
format (http://www.tptp.org). You can find a few examples in the
`tests` directory. All axioms and conjectures must be equations, but
you can freely use quantifiers. If it succeeds in proving your
problem, twee will print a human-readable proof.
