--optional[=DEPTH] will control the depth at which optional dependencies are printed. Its behavior is fairly simple. If the maximum depth is not yet exceeded, and it encounters an optional dependency, it will print it like a normal dependency except with an optional tag. A negative number means infinite depth.
