Making a lilypond-book (Modified by Will Oram)

[Will Oram]

I'm about ready to put three movements together inside one book 
assembled through lilypond-book. Having only toyed with l-book, I think 
I'll need some help.

Let's assume I want movements separated in subdirectories, and the .tex 
file in the top level. How would I get l-book to read ly files in a 
subdirectory? I don't think \lilypond {mvmt1/mvmt1.ly} works after 
trying it.

This is my sketch. ly-book chokes on it. (lilypond-bin couldn't find 
any of my included files. Changing all the \includes to begin with a 
mvmt1/... prefix helped a little. Now the error is 'programming error: 
Improbable offset for translation: setting to zero
Continuing; crossing fingers.')

Does anyone have suggestions, or just overall comments about the plan?

[PS: I have the opera.cls document class in place, so that's not the 
problem.]

\documentclass[a4paper]{opera}
     \begin{document}

     \lilypondfile{mvmt1/mvmt1.ly}
        \clearpage
        \lilypondfile{mvmt2/mvmt2.ly}
        \clearpage
        \lilypondfile{mvmt3/mvmt3.ly}
        \clearpage

     \end{document}
