  20 // Since this class swizzles a class method, it doesn't make sense to have more
  21 // than one instance of this class in existence at the same time.
  22 // The primary purpose of this class is to stub out the behavior of NSBundle for
  23 // AppKit, which makes assumptions about the functionality of +[NSBundle
  24 // mainBundle]. Code in Chrome should not require the use of this method, since
  25 // the NSBundle is always accessed through bundle_locations.h, and that NSBundle
  26 // can be directly stubbed.
