include header conflicts

[Kieren MacMillan]

Hello all!

I've got an individual .ly file for each cue (song or orchestral interlude) in 
my musical. I want to include them in a complete score .ly file, but when I do 
that the header variables conflict (e.g., the first or last 'title' or 'piece' 
value gets printed in the header of all scores).

It's probably something small that I'm doing wrong — so rather than try to 
build a minimal example, I was hoping someone out there might be able to 
diagnose the problem from past experience and give me a hint on how to solve it.

Thanks,
Kieren.
