const CFStringRef kCFBundleVersionKey; /* The version number of the bundle. For Mac OS 9 style version numbers (for example "2.5.3d5"), */ /* clients can use CFBundleGetVersionNumber() instead of accessing this key directly since that */ /* function will properly convert the version string into its compact integer representation. */
