[Boost-users] How do i access graph property?

Suppose I have defined the following graph:

typedef boost::adjacency_list<
    boost::setS,      // Adjacency list
    boost::setS,      // Vertex list
    boost::undirectedS,   // Undirected graph
    unsigned int,      // Vertex property (unique label)
    boost::no_property,   // Edge property
    unsigned int,      // Graph property (next unique label)
    boost::listS      // Edge list
 > graph;

How do I access the graph property? For the vertex property this is a 
very simple operation:

graph g = ...;
vertex_descriptor u = ...;
vertex_property label = g[u];

But I can't find a way to access property associated with my graph. How 
can I do this?
