I'm been busy for a while but I'm back in business now. PathZilla v6 is underway once more.
I have implemented industry support, but I would like to be able to handle ALL cargos not just raw ones.
Is there a way to find which input cargos are needed for an industry to generate a particular output cargo? i.e. when I provide steel to a factory, goods are produced. I dont need to also provide grain and livestock.
I know its pretty trivial with the default industries, but newindustries seems to be more complex. Unless I'm mistaken, in PBI a steel mill requires iron ore AND coal to produce steel.
Or am I just being stupid?

Thanks
