+/**
+ * Annotates the place with this annotation when a RootComponent is needed.
+ *
+ * <p>Usually users put this annotation on application class that is root of dependencies (the last
+ * thing to compile). The annotation processor will figure out what it needs to generate a variant
+ * root through dependencies.
+ *
+ * <p>Example:
+ *
+ * <pre>
+ * <code>
+ * @DialerRootComponent(variant = DialerVariant.DIALER_AOSP)
+ * public class RootDialerAosp {}
+ * </code>
+ * </pre>
