// .NAME vtkXMLPPolyDataWriter - Write PVTK XML PolyData files.
// .SECTION Description
// vtkXMLPPolyDataWriter writes the PVTK XML PolyData file format.
// One poly data input can be written into a parallel file format with
// any number of pieces spread across files.  The standard extension
// for this writer's file format is "pvtp".  This writer uses
// vtkXMLPolyDataWriter to write the individual piece files.
