'''ACL2''' ('''A Computational Logic for Applicative Common Lisp''') is a [[software]] system consisting of a [[programming language]], an extensible theory in a [[first-order logic]], and an [[automated theorem prover]]. ACL2 is designed to support [[automated reasoning]] in inductive logical theories, mostly for software and [[hardware verification]]. The input language and implementation of ACL2 are written in [[Common Lisp]]. ACL2 is [[free and open-source software]].
