Z3 is an automated theorem prover and satisfiability modulo theories
(SMT) solver. Given a formula in first-order logic, it attempts
to either prove the formula or find a counterexample. Z3 supports
arithmetic, reasoning about arrays, and several other built-in
theories. Input problems are written in SMT-LIB format.

This package includes the z3 program as well as the C++, Python2, and
Python3 APIs.
