\bookpart and the "\include trouble"

[Federico Bruni]

[sorry for opening a new thread on the same matter, but I thought a 
more precise subject was needed]

I'm trying to compile several different scores into a book, using a 
new file (book.ly) and \bookpart.

I can't get it working if in the scores there are some \include.
The error messages says there's a synthax error in the included file 
(even english.ly!?).

So it's weird, I can't find a solution anywhere.

Below is my book.ly
You find it attached (with 2 included files, if you want to test it 
yourself).

Thanks for help,
Federico


\version "2.13.3"

\book {

  \markuplines \table-of-contents
  \pageBreak

   \bookpart{
      \tocItem \markup "Score 1"
       \include "file1.ly"
   }
   \bookpart{
      \tocItem \markup "Score 2"
       \include "file2.ly"
   }
}
