  * **Note**: If you already have a `build.dart` in your application, we
  * recommend to use the `package:polymer/builder.dart` library instead.
 
  * Temporary deploy command used to create a version of the app that can be
  * compiled with dart2js and deployed. Following pub layout conventions, this
  * script will treat any HTML file under a package 'web/' and 'test/'
  * directories as entry points.
  *
  * From an application package you can run deploy by creating a small program
  * as follows:
  *
  *    import "package:polymer/deploy.dart" as deploy;
  *    main() => deploy.main();
  *
  * This library should go away once `pub deploy` can be configured to run
  * barback transformers.
