A new proof manager and graphic interface for the larch prover
We present plp, a proof management system and graphic interface for the “Larch Prover” (LP). The system provides additional support for interactive use of LP, by letting the user control the order in which goals are proved. We offer improved ways to investigate, compare and communicate proofs by allowing independent attempts at proving a goal, a better access to the information associated with goals and an additional script mechanism. All the features are accessible through a graphic system that makes the proof structure accessible to the user.
