[Boost-users] How to use make_bfs_visitor (and/or time_stamper)

I figured out how to make a custom visitor for a BFS search: http://programmingexamples.net/index.php?title=CPP/Boost/BGL/BreadthFirstSea... but now I am trying to figure out what make_bfs_visitor does, and use it, potentially in conjunction with boost::time_stamper http://programmingexamples.net/index.php?title=CPP/Boost/BGL/MakeBFSVisitor Would anyone mind taking a look there to see where I am going wrong. You can see I tried a lot of things that didn't work :) Thanks, David
