%description
Z3 is a satisfiability modulo theories (SMT) solver; given a set of
constraints with variables, it reports a set of values for those
variables that would meet the constraints.  The Z3 input format is an
extension of the one defined by the SMT-LIB 2.0 standard.  Z3 supports
arithmetic, fixed-size bit-vectors, extensional arrays, datatypes,
uninterpreted functions, and quantifiers.
