Given a directed graph $D$ and a specified vertex $r$, I would like the list of all directed spanning trees, or arborescences, rooted in $r$. This can be computed by induction as is done for spanning trees in undirected graphs with the spanning_trees method of the class Graph, but it seems like this has not been implemented for directed graphs.
