README

The `logicproof' package This package provides environments for creating Fitch-style box proofs for propositional and predicate logic. In this style, each line of the proof contains a statement and a justification, and subproofs within the larger proof are enclosed in a box. For an example of this proof style, see the manual in logicproof.pdf. This code is released under the LaTeX Project Public License.

## 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.
