string UploadPack get; set;
Not implemented
Use this to specify the path to 'git-upload-pack' on the
remote side, if it is not found on your $PATH. Some
installations of sshd ignores the user's environment
setup scripts for login shells (e.g. .bash_profile) and
your privately installed git may not be found on the system
default $PATH. Another workaround suggested is to set
up your $PATH in ".bashrc", but this flag is for people
who do not want to pay the overhead for non-interactive
shells, but prefer having a lean .bashrc file (they set most of
the things up in .bash_profile).
