A Brief Overview

Coq [37] is a proof assistant with which students, researchers, or engineers can express specifications and develop programs that fulfill these specifications. This tool is well adapted to develop programs for which absolute trust is required: for example, in telecommunication, transportation, energy, banking, etc. In these domains the need for programs that rigorously conform to specifications justifies the effort required to verify these programs formally. We shall see in this book how a proof assistant like Coq can make this work easier.
