Don't forget redo. The idea of enumerating build-time dependencies by tracing dynamic loader activity I recall was famously done by memoize.py, which comes from before or around the same time as tup's initial bare-bones commit was made. It's doubtlessly much older, of course. I've read that a SunOS component or some other Sun product related to build infrastructure did the same, but I cannot find any references.
