-// OverlayableContentsController manages the display of up to two tab contents
-// views. It is primarily for use with Instant results. This class supports the
-// notion of an "active" view vs. an "overlay" tab contents view.
+// OverlayableContentsController is an obsolete wrapper holding the view where a
+// tab's WebContents is displayed. In the old Chrome Instant implementation it
+// multiplexed between the tab's contents and an overlay's contents. Now there
+// is no overlay, but ripping this class out entirely is hard.
 //
-// The "active" view is a container view that can be retrieved using
-// |-activeContainer|. Its contents are meant to be managed by an external
-// class.
-//
-// The "overlay" can be set using |-showOverlay:| and |-hideOverlay|. When an
-// overlay is set, the active view is hidden (but stays in the view hierarchy).
-// When the overlay is removed, the active view is reshown.
+// TODO(sail): Remove this class and replace it with something saner.
