Why3 is a platform for deductive program verification. It provides
a rich language for specification and programming, called WhyML,
and relies on external theorem provers, both automated and interactive,
to discharge verification conditions. Why3 comes with a standard
library of logical theories (integer and real arithmetic, Boolean
operations, sets and maps, etc.) and basic programming data structures
(arrays, queues, hash tables, etc.). A user can write WhyML programs
directly and get correct-by-construction OCaml programs through an
automated extraction mechanism. WhyML is also used as an intermediate
language for the verification of C, Java, or Ada programs.
