+  <longdescription>
+    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.
