This is in our style guide, we can cheaply enforce it, let's do it.
```
$ pre-commit
check-case-conflicts.....................................................Passed
check-executables-have-shebangs..........................................Passed
check-headers............................................................Failed
- hook id: check-headers
- exit code: 1
Missing pattern @file in file src/libexpr/value.hh
We found some header files that don't conform to the style guide.
The Lix style guide requests that header files:
- Begin with `#pragma once` so they only get parsed once
- Contain a doxygen comment (`/**` or `///`) containing `@file`, for
example, `///@file`, which will make doxygen generate docs for them.
When adding that, consider also adding a `@brief` with a sentence
explaining what the header is for.
