Re: Extracting a "score diff" from two [or more] Lilypond sources

[Valentin Petzel]

Hi Kieren,

What about this: We could have a small script that takes a diff of the new file 
and the old file and creates a new version of the new file where all changed 
(music) lines are tagged. This way we do not need to try to match two streams 
against the other one, but we do in already know more or less the parts that 
have changed and the parts that haven’t.

Cheers,
Valentin
