+/**
+ * Transformer which generates type factories for static injection.
+ *
+ * Types which are considered injectable can be annotated in the following ways:
+ *
+ * * Use the @inject annotation on a class from `package:inject/inject.dart`
+ *     @inject
+ *     class Engine {}
+ *
+ * or on the constructor:
+ *
+ *     class Engine {
+ *       @inject
+ *       Engine();
+ *     }
+ *
+ * * Define a custom annotation in pubspec.yaml
+ *
+ *     transformers:
+ *     - di:
+ *       injectable_annotations:
+ *       - library_name.ClassName
+ *       - library_name.constInstance
+ *
+ * Annotate constructors or classes with those annotations
+ *
+ *     @ClassName()
+ *     class Engine {}
+ *
+ *     class Engine {
+ *       @constInstance
+ *       Engine();
+ *     }
+ *
+ * * Use package:di's Injectables
+ *
+ *     @Injectables(const [Engine])
+ *     library my_lib;
+ *
+ *     import 'package:di/annotations.dart';
+ *
+ *     class Engine {}
+ *
+ * * Specify injected types via pubspec.yaml
+ *
+ *     transformers:
+ *     - di:
+ *       injected_types:
+ *       - library_name.Engine
