AUTHOR

       The    svgalib    joystick    handler    was    mostly    done    by   Daniel   Engstr\"om
       <daniel.engstrom@riksnett.no>.  Multiple joystick, VC switching support and code  to  glue
       it  into  svgalib  by  Michael  Weller <eowmob@exp-math.uni-essen.de>. Part of the code is
       based on code from C. Smith and Vojtech Pavlik.
