I have

struct vertex_properties
{
    blah blah
}

struct edge_properties
{
    blah blah
}

struct graph_properties
{

  int bobo;

}


typedef adjacency_list < vecS, vecS, bidirectionalS,
        property< vertex_predecessor_t, vertex_t, vertex_properties >,
        property< edge_reverse_t, edge_t, edge_properties >,
        graph_properties
                > graph_t;

graph_t g;

But how can I access bobo?

g.bobo does not compile (otherwise OK).

thanks
