+// .NAME vtkPiecewisePointHandleItem - a vtkContextItem that draws handles
+//       around a point of a piecewise function
+//
+// .SECTION Description
+// This is a vtkContextItem that can be placed into a vtkContextScene. It draws
+// handles around a given point of a piecewise function so that the curve can
+// be adjusted using these handles.
