-/// Polymer.dart, the next evolution of Web UI,
-/// is an in-progress Dart port of the
-/// [Polymer project](http://www.polymer-project.org/).
-/// Polymer.dart compiles to JavaScript and runs across the modern web.
-///
-/// To use polymer.dart in your application,
-/// first add a
-/// [dependency](http://pub.dartlang.org/doc/dependencies.html)
-/// to the app's pubspec.yaml file.
-/// Instead of using the open-ended `any` version specifier,
-/// we recommend using a range of version numbers, as in this example:
-///
-///     dependencies:
-///       polymer: '>=0.7.1 <0.8'
-///
-/// Then import the library into your application:
-///
-///     import 'package:polymer/polymer.dart';
-///

-/// Example code, project status, and
-/// information about how to get started using Polymer.dart in your apps.

-// *** Important Note ***
-// This import is automatically replaced when calling pub build by the
-// mirrors_remover transformer. The transformer will remove any dependencies on
-// dart:mirrors in deployed polymer apps. This and the import to
-// mirror_loader.dart below should be updated in sync with changed in
-// lib/src/build/mirrors_remover.dart.
-//
-// Technically this annotation is not needed now that we have codegen for
-// expressions, but our test bots don't run pub-build yet. Until then, tests
-// might (transitively) have an import to smoke.mirrors, even though the code is
-// completely dead. This @MirrorsUsed annotation helps reduce the load on our
-// bots.
