+# Annotations for Static Analysis
+
+This package defines annotations that can be used by the tools that are shipped
+with the Dart SDK.
+
+## Library Structure
+
+The annotations in this package are defined in two libraries.
+
+The library in `meta.dart` defines annotations that can be used by static
+analysis tools to provide a more complete analysis of the code that uses them.
+Within the SDK, these tools include the command-line analyzer (`dartanalyzer`)
+and the analysis server that is used to power many of the Dart-enabled
+development tools.
+
+The library in `dart2js.dart` defines annotations that provide hints to dart2js
+to improve the quality of the JavaScript code that it produces. These
+annotations are currently experimental and might be removed in a future version
+of this package.
+

+
+Questions and discussions are welcome at the
