    // Even with `.gitignore` and the `exclude` in the `Cargo.toml`, the generated parser can still
    // end up in the source directory. This could happen when `cargo build` builds the file out of
    // the Cargo cache (`$HOME/.cargo/registrysrc`), and the build script would then put its output
    // in that cached source directory because of https://github.com/lalrpop/lalrpop/issues/280.
    // Later runs of `cargo vendor` then copy the source from that directory, including the 
    // generated file.
