Build procedure has slightly changed, adjusted ebuild to follow *otter-3.2.ebuild (16 May 2003) 16 May 2003; George Shapovalov Manifest, otter-3.2.ebuild, files/{digest-otter-3.2} : initial release (#19036) Otter is designed to prove theorems stated in first-order logic with equality. Otter's inference rules are based on resolution and paramodulation, and it includes facilities for term rewriting, term orderings, Knuth-Bendix completion, weighting, and strategies for directing and restricting searches for proofs. Otter can also be used as a symbolic calculator and has an embedded equational programming system. Otter is a fourth-generation Argonne National Laboratory deduction system whose ancestors (dating from the early 1960s) include the TP series, NIUTP, AURA, and ITP. ebuild submitted by Meghan Claire Pike
