aris: GNU Aris is a sequential proof program, designed to assist anyone
aris: interested in solving logical proofs. Aris supports both propositional
aris: and predicate logic, as well as Boolean algebra and arithmetical logic
aris: in the form of abstract sequences. It uses a predefined set of both
