[Boost-users] Extended Subgraph

Hi! Is there an extended version of subgraph.hpp available somewhere, which is able to remove subgraphs. I need something like: subgraph p(5) subgraph c = p.create_subgraph(); v1 = add_vertex(c); v2 = add_vertex(p); add_edge(v1, v2); p.remove_subgraph(c); In this case c should be removed from p and edge (v1,v2) and v1 should be destroyed. Thanks, Alex
