As part of my previous thinking around copyright, I came around to the value of per-file “hey, I’m part of a project using license X” statements, as promoted by efforts like [https://reuse.software](https://reuse.software).

The main reason against it IMO is the hassle, so I once again ignored [xkcd: Is It Worth the Time?](https://xkcd.com/1205) and wrote [tec/headlice: Automatic license headers, and other licensing utilities - Code by TEC](https://code.tecosaur.net/tec/headlice), which entirely handles it in the background.
