/// `prost_build` generates files in the output directory, which means that if we want
/// to use it, we would need the protoc compiler as a build dependency.
/// To get around this, we need run the build script and manually copy the generated files
/// into the `src` folder. To do so, uncomment the below lines, then copy the files from the
/// output directory into the `src/proto` folder. The path to the output directory
/// will be printed in the terminal.
