This example provides a function to typeset a hairpin (de)crescendo
with some additional text below it, such as @qq{molto} or @qq{poco}.
+The added text will change the direction according to the direction of
+the hairpin. The Hairpin is aligned to DynamicText.
+
The example also illustrates how to modify the way an object is
normally printed, using some Scheme code.
