+    Kissat is a "keep it simple and clean bare metal SAT solver" written in C.
+    It is a port of CaDiCaL back to C with improved data structures, better
+    scheduling of inprocessing and optimized algorithms and implementation.
+    Coincidentally "kissat" also means "cats" in Finnish.

+  <longdescription>
+    Z3 is an efficient Satisfiability Modulo Theories (SMT) solver from
+    Microsoft Research. Z3 is a solver for symbolic logic, a foundation for
+    many software engineering tools. SMT solvers rely on a tight integration of
+    specialized engines of proof. Each engine owns a piece of the global puzzle
+    and implements specialized algorithms. For example, Z3’s engine for
+    arithmetic integrates Simplex, cuts and polynomial reasoning, while an
+    engine for strings are regular expressions integrate methods for symbolic
+    derivatives of regular languages. A theme shared among many of the
+    algorithms is how they exploit a duality between finding satisfying
+    solutions and finding refutation proofs. The solver also integrates engines
+    for global and local inferences and global propagation. Z3 is used in a
+    wide range of software engineering applications, ranging from program
+    verification, compiler validation, testing, fuzzing using dynamic symbolic
+    execution, model-based software development, network verification, and
+    optimization.
