That will almost certainly not be a problem. I'm working on reading stuff
into git-specific structures and then updating those structures. I doubt
any such code exists outside git. If it does, it's more likely derived
from git than the other way around.

It's also worth noting that I'm aiming for the really low-level core
stuff at first. It would be beneficial to get such simple things going
as updating the index (with an entire file) and then creating a commit
from that index. Such a thing would definitely be enough for (very basic)
IDE integration, and then we can build further on that but utilizing
developers from other projects than the git developer community.
