"To see more real-world examples of makefiles, see my [World Atlas](https://github.com/mbostock/world-atlas) and [U.S. Atlas](https://github.com/topojson/us-atlas) projects, which contain makefiles for generating TopoJSON from Natural Earth, the National Atlas, the Census Bureau, and other sources."
I checked those repositories because the descriptions of the makefiles sound interesting, but I couldn't find the makefiles. Am I looking wrong?
