README

        
What4 is a library for representing symbolic terms and communicating with

satisfiability and SMT solvers (e.g. Yices and Z3).

It was originally a part of the [Crucible](https://github.com/GaloisInc/crucible)

project, but has found use cases that are independent of its original

purpose as the representation language for the Crucible symbolic

simulator, and has thus been split out into a separate repository.

For an overview of What4 and how to use it, please see the

package-level [README](what4/README.md).

This material is based upon work supported by the Defense Advanced

Research Projects Agency (DARPA) under Contract No. HR0011-19-C-0070.
