+description: """
+A library of formalized graph theory results, including various
+standard results from the literature (e.g., Menger’s Theorem, Hall’s
+Marriage Theorem, and the excluded minor characterization of
+treewidth-two graphs) as well as some more recent results arising
+from the study of relation algebra within the ERC CoVeCe project
+(e.g., soundness and completeness of an axiomatization of graph
+isomorphism)."""
