[Boost-users] newbie weighted edges question

Hello everyone, I am new at using Boost libraries and was hoping that someone could give me some pointers how to start.The problem that I want to solve is as follows: I want to build a directed graph model with edges that are weighted.But instead of having one weight each edge is suppose to have 2 weights, each representing a different parameter in my graph model.The weights are to be used separately for different functions. Also, this is trivial but a pointer would certainly help. I would like to take each vertice in the graph and ¨know¨ its immediate neighbours. Thanks in advance. Fahad
