-// -----------------------------------------------------------------------------
+// RenderWidgetHostViewChildFrame implements the view for a RenderWidgetHost
+// associated with content being rendered in a separate process from
+// content that is embedding it. This is not a platform-specific class; rather,
+// the embedding renderer process implements the platform containing the
+// widget, and the top-level frame's RenderWidgetHostView will ultimately
+// manage all native widget interaction.
+//
 // See comments in render_widget_host_view.h about this class and its members.
-// This version is for the webview plugin which handles a lot of the
-// functionality in a diffent place and isn't platform specific.
-//
-// Some elements that are platform specific will be deal with by delegating
-// the relevant calls to the platform view.
