+        # options parameter must include values for :aws_access_key_id and
+        # :aws_secret_access_key in order to create a connection
+        #
+        # ==== Examples
+        #   elb = CloudWatch.new(
+        #    :aws_access_key_id => your_aws_access_key_id,
+        #    :aws_secret_access_key => your_aws_secret_access_key
+        #   )
+        #
+        # ==== Parameters
+        # * options<~Hash> - config arguments for connection.  Defaults to {}.
+        #   * region<~String> - optional region to use, in ['eu-west-1', 'us-east-1', 'us-west-1', 'ap-southeast-1', 'ap-northeast-1']
+        #
+        # ==== Returns
+        # * CloudWatch object with connection to AWS.
