logicproof – Box proofs for propositional and predicate logic

A common style of proof used in propositional and predicate logic is Fitch proofs, in which each line of the proof has a statement and a justification, and subproofs within a larger proof have boxes around them.

The package provides environments for typesetting such proofs and boxes. It creates proofs in a style similar to that used in “Logic in Computer Science” by Huth and Ryan.
