In particular, Coq allows: * the definition of functions or predicates, * to state mathematical theorems and software specifications, * to develop interactively formal proofs of these theorems, * to check these proofs by a small certification "kernel". Coq is based on a logical framework called "Calculus of Inductive Constructions" extended by a modular development system for theories. </longdescription> <use> <flag name="camlp5">Build using camlp5.
