-// An interface implemented by objects wishing to control an InfoBar.
-// Implementing this interface is not sufficient to use an InfoBar, since it
-// does not map to a specific InfoBar type. Instead, you must implement either
-// LinkInfoBarDelegate or ConfirmInfoBarDelegate, or override with your own
-// delegate for your own InfoBar variety.
-//
-// --- WARNING ---
-// When creating your InfoBarDelegate subclass, it is recommended that you
-// design it such that you instantiate a brand new delegate for every call to
-// AddInfoBar, rather than re-using/sharing a delegate object. Otherwise,
-// you need to consider the fact that more than one InfoBar instance can exist
-// and reference the same delegate -- even though it is also true that we only
-// ever fully show one infobar (they don't stack). The dual-references occur
-// because a second InfoBar can be added while the first one is in the process
-// of closing (the animations). This can cause problems because when the first
-// one does finally fully close InfoBarDelegate::InfoBarClosed() is called,
-// and the delegate is free to clean itself up or reset state, which may have
-// fatal consequences for the InfoBar that was in the process of opening (or is
-// now fully opened) -- it is referencing a delegate that may not even exist
-// anymore.
-// As such, it is generally much safer to dedicate a delegate instance to
-// AddInfoBar!
