+ * Provides entity base field override destination plugin.
+ *
+ * Base fields are non-configurable fields that always exist on a given entity
+ * type, like the 'title', 'created' and 'sticky' fields of the 'node' entity
+ * type. Some entity types can have bundles, for example the node content types.
+ * The base fields exist on all bundles but the bundles can override the
+ * definitions. For example, the label for node 'title' base field can be
+ * different on different content types.
+ *
+ * Example:
+ *
+ * The example below migrates the node 'sticky' settings for each content type.
+ * @code
