Licence?

Hi Jack,

Thank you for your work on this project and others. I'm referencing it as a real world sample of Pgxpool and Chi, as well as directly using your `github.com/jackc/booklog/bee` module in our project.

Could I trouble you to please add a licence file if applicable?

No file or test is named. Check the repository root and project metadata for an existing license or stated licensing preference, then confirm the appropriate license with the maintainer. Done means the repository includes a clearly identified license file covering the project and its Go module.
