       grail-test-3-1 - dump grail v3 events


       grail-test-3-1 window


       This  tool  prints  grail  v3  events to stdout.  It requires an X11 server which supports
       multi-touch through XInput 2.2.  It subscribes to gestures with 3 touch start and max, but
       with  a minimum of 1 touch.  The grail-test-3-1 tool helps test continuation through touch
       count changes.
