+# This example shows how to extract portions of an unstructured grid
+# using vtkExtractUnstructuredGrid. vtkConnectivityFilter is also used
+# to extract connected components.
+#
+# The data found here represents a blow molding process. Blow molding
+# requires a mold and parison (hot, viscous plastic) which is shaped
+# by the mold into the final form. The data file contains several steps
+# in time for the analysis.

+# Create a reader to read the unstructured grid data. We use a
