description:
   Twee is an experimental equational theorem prover based on
   Knuth-Bendix completion.
   .
   Given a set of equational axioms and a set of equational
   conjectures it will try to prove the conjectures.
   It will terminate if the conjectures are true but normally
   fail to terminate if they are false.
   .
   The input problem should be in TPTP format (see
   http://www.tptp.org). You can use types and quantifiers, but apart
   from that the problem must be equational.
