-A parser for [YAML](http://www.yaml.org/).
-
-Use `loadYaml` to load a single document, or `loadYamlStream` to load a
-stream of documents. For example:
-
-```dart
-import 'package:yaml/yaml.dart';
-
-main() {
-  var doc = loadYaml("YAML: YAML Ain't Markup Language");
-  print(doc['YAML']);
-}
-```
-
-This library currently doesn't support dumping to YAML. You should use
-`JSON.encode` from `dart:convert` instead:
-
-```dart
-import 'dart:convert';
-import 'package:yaml/yaml.dart';
-
-main() {
-  var doc = loadYaml("YAML: YAML Ain't Markup Language");
-  print(JSON.encode(doc));
-}
-```
-
-The source code for this package is at <http://code.google.com/p/dart>.
-Please file issues at <http://dartbug.com>. Other questions or comments can be
-directed to the Dart mailing list at <mailto:misc@dartlang.org>.
