+You need the iFeel linux kernel module from
+http://sourceforge.net/projects/tactile in order to use this external.
+
+The iFeel mouse uses periodic pulses to create the various haptic
+effects.

+------------------------------------------------------------------------------
+control type raw range pd range
+------------------------------------------------------------------------------
+strength of pulse 1-255 0 - 1
+delay between pulses 1-255 0 - infinite milliseconds
