-/// Experimental bootstrap to initialize polymer applications. This library is
-/// not used by default, and may be replaced by Dart code in the near future.
-///
-/// This script contains logic to bootstrap polymer apps during development. It
-/// internally discovers Dart script tags through HTML imports, and constructs
-/// a new entrypoint for the application that is then launched in an isolate.
-///
-/// For each script tag found, we will load the corresponding Dart library and
-/// execute all methods annotated with `@initMethod` and register all classes
-/// labeled with `@CustomTag`. We keep track of the order of imports and execute
-/// initializers in the same order.
-///
-/// You can this experimental bootstrap logic by including the
-/// polymer_experimental.html import, instead of polymer.html:
-///
-/// <link rel="import" href="packages/polymer/polymer_experimental.html">
-///
-/// This bootstrap replaces `initPolymer` so Dart code might need to be changed
-/// too. If you loaded init.dart directly, you can remove it. But if you invoke
-/// initPolymer in your main, you should remove that call and change to use
-/// `@initMethod` instead. The current bootstrap doesn't support having Dart
-/// script tags in the main page, so you may need to move some code into an HTML
-/// import. For example, If you need to run some initialization code before any
-/// other code is executed, include an HTML import to an html file with a
-/// "application/dart" script tag that contains an initializer
-/// method with the body of your old main, and make sure this tag is placed
-/// above other html-imports that load the rest of the application.
-/// Initialization methods are executed in the order in which they are
-/// discovered in the HTML document.
