" Describing what code does is very hard, and it would be easier to just publish it in stead.' Depends on what level you're describing it. "It does an FFT" or "it sorts" are pretty clear. It gets hairy if you describe the specific details of the implementations. But the implementation is likely irrelevant, because other scientists can choose any implementation. Even with complex models you ought to be able to piece much of them together out of descriptions at that higher level.
