 /// `build.dart` files. A `build.dart` file is a Dart script that can be invoked
 /// from the command line, but that can also invoked automatically by the Dart
 /// Editor whenever a file in your project changes or when selecting some menu

 ///   * `--changed file-path`: notify of a file change.
 ///   * `--removed file-path`: notify that a file was removed.
 ///   * `--clean`: remove temporary artifacts (if any)
 ///   * `--full`: build everything, similar to marking every file as changed
 ///   * `--machine`: produce output that can be parsed by tools, such as the
 ///     Dart Editor.
 ///   * `--deploy`: force deploy.
 ///   * `--no-js`: deploy replaces *.dart scripts with *.dart.js. You can turn
