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