What about lists? I'm thinking about this for some time now and I think lists are more flexible. At higher level we can easily generate a list of pages and in a lower level you can still split them up as needed. It would be basically the same structure, but you could use it everywhere with the same kind of operations. bye, Roman - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] Please read the FAQ at http://www.tux.org/lkml/
