linux - How can I get the comment of the current authorized_keys ssh key? - Super User[web search]

Edit: What I really need to know WHICH ssh key from authorized_keys has been used to identify the currently logged on user.
According to "man sshd":
I see that when I use ssh-keygen, the comment is usually the local identity of the user. Is there any way to access this value when I'm on the remote computer ? (Kind of like the SSH_CLIENT shell variable)
(Assuming I enforce the comment to be a remote identity of some sort, I would like to log this from a shell-script! This is on ubuntu)
