+.Sh NAME
+.Nm xtsscale
+.Nd X touch screen calibration tool
+.Sh SYNOPSIS
+.Nm xtsscale
+.Bk -words
+.Op Ar device
+.Ek
+.Sh DESCRIPTION
+.Nm
+is used interactively to calculate both the scaling and offset values which
+will make the pointer act at the indicated location on the screen.
+.Pp
+When good deviations are calculated from the selections made at these
+points,
+.Nm
+will exit and provide on standard output a result like the following:
+.Pp
+.Dl mouse.scale=200,3400,312,3672,1,1024,768
+.Pp
+.Sh SEE ALSO
+.Xr ioctl 2 ,
+.Xr uts 4 ,
+.Xr wscons 4 ,
+.Xr wsconsctl 8 ,
+.Xr X 7
+.Sh HISTORY
+The
+.Nm
+command appeared in
+.Ox 4.2 .
