install public ssh keys on remote servers

I have SSH access to many hundreds of servers and am regularly needing to log into new systems. My SSH key is available via ssh-agent thanks to the ssh-agent script I wrote. To make good use of ssh-agent, my SSH public key needs to be installed on the remote servers. I have had to do this often so today I polished up a shell script that automates the installation of your ssh key on remote servers. It is now fit for mass consumption.
