Hi, 

is there a way to use the graph-tool algorithms to test whether a connected
component of an undirected graph is 2-edge-connected, i.e., none of its
edges is a bridge which, if removed, would disconnect the component? 

Of course one can do that by filtering out edge by edge and labeling the
components of the resulting graphs, but that is probably not the most
efficient way.

Cheers,
Andre Vieira.
