  2D game development library.

  Gosu features easy to use and game-friendly interfaces to 2D graphics
  and text (accelerated by 3D hardware), sound samples and music as well as
  keyboard, mouse and gamepad/joystick input.

  Also includes demos for integration with RMagick, Chipmunk and Ruby-OpenGL.
