-// Represents a class used for creating an IShellLink object by the utility

-//   The arguments for the application.
-// * title (std::wstring)
-//   The string to be displayed in a JumpList.
-// * icon (std::wstring)
-//   The absolute path to an icon to be displayed in a JumpList.
-// * index (int)
-//   The icon index in the icon file. If an icon file consists of two or more
-//   icons, set this value to identify the icon. If an icon file consists of
-// one icon, this value is 0.
-// Even though an IShellLink also needs the absolute path to an application to
-// be executed, this class does not have any variables for it because our
-// utility functions always use "chrome.exe" as the application and we don't
-// need it.
