7. Arguments for Make • Ubiquitous • Stable • Self-contained •

   Established conventions ◦ make ◦ make test ◦ make clean

8. Advantages of Standardizing • Reduced project switching overhead • Shared

   Continuous Integration configuration • Easier build debugging

10. Features

11. Files and Timestamps • Create missing files • Traverse dependency
