  1. GNU Aris is a sequential proof program, designed to assist anyone
  2. interested in solving logical proofs. Aris supports both propositional
  3. and predicate logic, as well as Boolean algebra and arithmetical logic
  4. in the form of abstract sequences. It uses a predefined set of both
  5. inference and equivalence rules, however gives the user options to use
  6. older proofs as lemmas, including Isabelle's Isar proofs.
