 Z3 is a state-of-the-art theorem prover from Microsoft Research. It can be
 used to check the satisfiability of logical formulas over one or more
 theories. Z3 offers a compelling match for software analysis and verification
 tools, since several common software constructs map directly into supported
 theories.

 This package can be used to invoke Z3 via its C++ API.
