A pointer to them? You mean a SHA1 hash of them? or what? Where is the *real* data stored? The real files, the real patches? Are these somewhere completely outside of git?

Perhaps I'd understand this if you tell me what "recreate" means. If a have a SHA1 hash of a file, and I have the file, I can verify that said file has the SHA1 hash it's supposed to have, but I can't generate the file from it's hash...
Sorry for being stubbornly dumb, but you'll have a couple of us puzzling at the README ;-)
