git-lfs-transfer is the server-side implementation of Git LFS using the SSH protocol.
git-lfs-transfer <git-dir> <operation>
Invoked by Git LFS client and updates the repository with the blob files from the remote end.
The command is usually not invoked directly by the end user. The UI for the GIT LFS SSH protocol is on the client side, and the program pair is meant to be used to push/pull updates to remote repository.
