```suggestion
	vinstall spooles.a 644 usr/lib
	for file in *.h; do
		vinstall ${file} 644 usr/include/$pkgname
	done
	for file in */*.h; do
		vinstall ${file} 644 "usr/include/$pkgname/$(dirname $file)"
	done
```
I guess they both work, but I think this feels better idk

also the lib should be installed
