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.
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.
