  80 /** Test to create a writer document and insert an OLE Chart.
  81
  82     Be careful!  This does not really work.  The Writer currently has no
  83     interface for dealing with OLE objects.  You can add an OLE shape to the
  84     Writer's drawing layer, but it is not treated correctly as OLE object.
  85     Thus, you can not activate the chart by double-clicking.  The office may
  86     also crash when the document is closed!
