+  <longdescription>
+    Dafny is a verification-ready programming language. As you type in your
+    program, Dafny's verifier constantly looks over your shoulder, flags any
+    errors, shows you counterexamples, and congratulates you when your code
+    matches your specifications. When you're done, Dafny can compile your code
+    to C#, Java, JavaScript or Go (more to come!), so it can integrate with
+    your existing workflow. Dafny will give you assurance that your code meets
+    the specifications you write, while letting you write both code and
+    specifications in the Dafny programming language itself. Since verification
+    is an integral part of development, it will thus reduce the risk of costly
+    late-stage bugs that are typically missed by testing. Dafny has support for
+    common programming concepts such as classes and trait inheritance,
+    inductive datatypes that can have methods and are suitable for pattern
+    matching, lazily unbounded datatypes, subset types e.g. for bounded
+    integers, lambdas, and immutable and mutable data structures. Dafny also
+    offers an extensive toolbox for mathematical proofs, such as unbounded and
+    bounded quantifiers, calculational proofs, pre- and post-conditions,
+    termination conditions, loop invariants, and read/write specifications.
