 // On Mac, some infobars are still used that have been migrated to a bubble UI
 // on other views platforms. When building the toolkit-views browser window on
 // Mac, the bubble UI can be used, but interfaces built for Cocoa on Mac still
 // depend on symbols to provide infobars. This file provides the symbols wanted
 // elsewhere for OS_MACOSX, but aren't otherwise needed for a views browser.
 // TODO(tapted): Delete this file when Mac uses the bubbles by default.
