## Third party code

It can be updated with the following command:

```

This project contains the [ANTLR example grammars](https://github.com/antlr/grammars-v4) as a git subtree under [third_party/antlr_grammars_v4](third_party/antlr_grammars_v4). Please see the individual grammar files for license and author information.

They can be updated with the following command:

```bash
