+-- |Make a greedy resource node.
+--
+-- Say a client is trying to access \"\/aaa\/bbb\/ccc\' while there is
+-- no resource node at the path. If there are greedy resource nodes at
+-- \"\/aaa\/bbb\", \"\/aaa\" or \"/\" they will be chosen instead as a
+-- fallback. Greedy resource nodes are searched in depth-first order.
