+  <longdescription>
+    Yices 2 is an SMT solver that decides the satisfiability of formulas
+    containing uninterpreted function symbols with equality, real and integer
+    arithmetic, bitvectors, scalar types, and tuples. Yices 2 supports both
+    linear and nonlinear arithmetic. Yices 2 can process input written in the
+    SMT-LIB notation (both versions 2.0 and 1.2 are supported). Alternatively,
+    you can write specifications using Yices 2's own specification language,
+    which includes tuples and scalar types. You can also use Yices 2 as a
+    library in your software.
