+Bonus Tutorial: Using generators to return result bodies
+
+Instead of returning a complete result string, you can use the yield
+statement to return one result part after another. This may be convenient
+in situations where using a template package like CherryPy or Cheetah
+would be overkill, and messy string concatenation too uncool. ;-)
