+ * #GtkSortListModel is a list model that takes a list model and

+ * #GtkSortListModel is a generic model and because of that it
+ * cannot take advantage of any external knowledge when sorting.
+ * If you run into performance issues with #GtkSortListModel, it
+ * is strongly recommended that you write your own sorting list
+ * model.
