+/// 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.
