On top of this nondeterministic substrate, Screamer provides a +comprehensive constraint programming language in which one can formulate and +solve mixed systems of numeric and symbolic constraints. Together, these two +levels augment Common Lisp with practically all of the functionality of both +Prolog and constraint logic programming languages such as CHiP and CLP(R). +Furthermore, Screamer is fully integrated with Common Lisp.
