+ * need to use some of its interfaces. Otherwise this header provides all of
+ * the expected interfaces.
+ *
+ * When clang modules are enabled, this header is a textual header to support
+ * the multiple include behavior. As such, it doesn't directly declare anything
+ * so that it doesn't add duplicate declarations to all of its includers'
