// .NAME vtkTransmitUnstructuredGridPiece - Return specified piece, including specified

// number of ghost levels.

|
// .SECTION Description
|
|
// This filter updates the appropriate piece by requesting the piece from
|
|
// process 0. Process 0 always updates all of the data. It is important that
|
|
// Execute get called on all processes, otherwise the filter will deadlock.
