[Boost-users] Specifying starting vertex in depth_first_search

I'm trying to use depth_first_search() and I want to specify the start node. However, I can't seem to specify the color map correctly. I'm encountering the same problem as described in one of the archive posts at ( http://groups.google.ca/group/boost-list/browse_thread/thread/679106e227e0eb... ). Any small examples available?
