+This file contains externs for use with the Closure compiler (aka JSCompiler).
+Passing these files to the --externs parameter of a compiler pass allows using
+type annotations for AngularJS objects. For example, Angular's $scope objects
+can be annotated as:
+  /** @type {angular.Scope} */ var scope = $scope;
+
+This allows JSCompiler to type check accesses to scope, give warnings about
+missing methods or incorrect arguments, and also prevents renaming of property
+accesses with advanced compilation.
+
+The externs are incomplete and maintained on an as-needed basis, but strive to
+be correct. Externs for individual modules should be added in separate files.
+
+See https://developers.google.com/closure/compiler/
