openbook.ly extraire et transposer

[jojo-monk]

Bonjour,

J'ai découvert ici :  https://github.com/veltzer/openbook
<https://github.com/veltzer/openbook>  
openbook.ly qui est un real book open source.

Je souhaiterais extraire un morceau du book et le transposer, existe-t-il un
moyen simple ?
Comment faire pour que lilypond ne compile que la partie qui m’intéresse ?

exemple : si je veux extraire cette partie :
\bookpart {

% this causes the variables to be defined...












% now play with the variables that depend on language









\tocItem \markup "The Girl From Ipanema / Antonio Carlos Jobim , Vincius De
Moraes, Norman Gimbel"

% this is just a small space, maybe we should replace this with a page

J'aimerais aussi rajouter mes propres partitions à l'openbook, le problème
c'est que je n'ai pas du tout la même manière de coder...

Merci
