 This is an API module. You only need to enable it if a module depends on it or
 you are interested in using it for development.

+Advanced usage:

+You can optimize cache clearing performance by setting the variable
+'entity_rebuild_on_flush' to FALSE. This skips rebuilding of feature
+components and exported entities during cache flushing. Instead, it is triggered
+by the features module only; e.g., when features are reverted.
