val of_universe : Cudf.universe -> t

Build a graph from a CUDF universe. Warning: dependency edges are towards the dependency, which is the reverse of what happens in the action graph.

val transitive_closure : t -> t

Return the transitive closure of g

val mirror : t -> t

Reverse the direction of all edges
