QStick is a program which uses the XTest extension in XFree86 to send keyboard messages to an X server from a Linux-supported joystick. The program consists of the KBStick executable which reads joystick input and dispatches keypress messages to X, and the QStick shell script which configures environment varibles read by the executable to assign X KeyCodes to the joystick directions & button presses.
