synopsis: "A Coq toolkit for graph theory"
description: """
This library offers inductive definitions of basics
in graph theory. The goal is to offer the possibility to write proofs
and programs on graphs in the same formalism : the Coq language.
It now contains : vertices, arcs, edges, degrees, graphs, directed
graphs,
paths, acyclic graphs, connected graphs and tree."""
