+Description
+===========
+  This application applies raw forces to a force feedback input device, 
+  illustrating how a simulator-type application can use force feedback to 
+  generate forces computed by a physics engine.
+
+  You must have a force feedback device connected to your system in order to 
+  run the application.

+
+User's Guide
+============
+  When you run the application, it displays a window with a crosshair and a 
+  black spot in it. Click the mouse anywhere within the window's client area to 
+  move the black spot. (Note that moving the device itself does not do 
+  anything.) FFConst exerts a constant force on the device from the 
+  direction of the spot, in proportion to the distance from the crosshair. You 
+  can also hold down the mouse button and move the spot continuously.
+
+Programming Notes
+=================
+  This sample program enumerates the input devices and acquires the first 
+  force-feedback device that it finds. If none are detected, it displays a 
+  message and terminates.
+
+  When the user moves the black spot, the joySetForcesXY function converts the 
+  cursor coordinates to a force direction and magnitude. This data is used to 
+  modify the parameters of the constant force effect.
