Thank you very much for the suggestion, Joe. However, in LilyPond
2.11.12, if I add a layout section such as you suggested above, there is
an error message when I invoke LilyPond to process the file--

However, if I comment-out the layout section (with %{ %}), as in the
attached file, no error message occurs.
