+ IVy is a research tool intended to allow interactive development of
+ protocols and their proofs of correctness and to provide a platform
+ for developing and experimenting with automated proof techniques. In
+ particular, IVy provides interactive visualization of automated
+ proofs, and supports a use model in which the human protocol
+ designer and the automated tool interact to expose errors and prove
+ correctness.
