Git + LilyPond

[Peter Bjuhr]

Hi all,

I have a question for those who use version control (and especially Git) 
with LilyPond:

When I write a new piece (or rather when a first version is written) I'd 
like to edit this as a single repo. But when it's (more) finished I 
think it would be better to collect it with other pieces in a larger 
repo (with the history intact of course). How can I do this? Is it a 
good idea?

I have some clues how to achieve this (especially with submodules), but 
I'd like to hear your experiences and tips!

(I vaguely remember some similar discussion about this!??)

Best
Peter
