LilyPond-Book and \include statements

[Br. Samuel Springuel]

Attached is a small sample project which attempts to exploit the 
\include statement in lilypond in a lilypond-book project.  The goal 
(and why I have two scores in this small sample) is to be able to place 
in Format.lyi those pieces of the lilypond code (such as font selection, 
or the definition of certain symbols) which should apply to every 
snippet in the final project.

If I run "lilypond-book Main.lytex" everything works as expected. 
However, this, creates lots of files and folders in the working 
directory, especially on large projects.  As a result, I'd like to make 
use of the --output and --lily-output-dir options to create 
subdirectories where these files can be placed (leaving the top 
directory relatively clean).  However, when I try to enable either of 
these options (as well as both), lilypond complains that it cannot find 
Format.lyi.  Specifically I get the following:

Using the "--output Main-out" option (or both simultaneously) yields a 
similar output.

Does anyone know why this might be happening and what I can do to fix it?

Note: While I will eventually be trying to make use of the 
LilyPond-Book.engine in TeXShop (hence the first line in the lytex file) 
for the moment I'm running lilypond-book from the command line in order 
to try and figure out this error.
