      <application>Qt5</application> is a cross-platform application
      framework that is widely used for developing application software
      with a graphical user interface (GUI) (in which cases
      <application>Qt5</application> is classified as a widget toolkit), and
      also used for developing non-GUI programs such as command-line tools
      and consoles for servers.
