 /**
  * Common logic to make it easy to create a `build.dart` for your project.
  *
  * The `build.dart` script is invoked automatically by the Editor whenever a
  * file in the project changes. It must be placed in the root of a project
  * (where pubspec.yaml lives) and should be named exactly 'build.dart'.
  *
  * A common `build.dart` would look as follows:
  *
  *     import 'dart:io';
- *     import 'package:web_components/component_build.dart';
+ *     import 'package:web_ui/component_build.dart';
  *
  *     main() => build(new Options().arguments, ['web/main.html']);
  *
  *
