+$w.text insert end "which results in relatively large gaps between " spacing
+$w.text insert end "the paragraphs.  Spacing2 is set to 2 points, " spacing
+$w.text insert end "which results in just a bit of extra space " spacing
+$w.text insert end "within a pararaph.  Spacing3 isn't used " spacing
+$w.text insert end "in this example.\n" spacing
+$w.text insert end "To see where the space is, select ranges of " spacing
