[Boost-users] Subgraphes and unneeded children

Hello, Can I reiterate my question about subgraphes: is there a way to delete unneeded children of the root subgraph? If I pass the root subgraph object to an algorithm, will it contain all the information about the subgraphes? If there is no way to delete unneeded children, how can I safely pass to an algorithm a set of subgraphes of the root graph ?? Also, are the bundled properties for subgraphes implemented yet in CVS ? Thank you, Jean-Noël
