[Boost-users] in_edges for a directedS adjacency_list

Hi, Is there a reason that the in_edges are not being maintained for a directedS adjacency_list? A quick look through implementations of boost::detail::add_edge(*) indicates correct maintainance for a bidirectional case, and reuse of the out_edges for the undirected case. I'm hopefully not missing something obvious to more enlightened souls and would appreciate any ideas to get the in_edges correctly for a directedS adjacency_list. thanks, -sr
