Why is this in my firewall-start script!? logger -t $(basename $0) $1

I added a few iptables rules yesterday, they did not work. Turns out, I had the command-

logger -t $(basename $0) $1

at the top of my firewall-start script. Of course, that kept the other rules from running because apparently that command hangs. I can't remember for the life of my why I would put that command in firewall-start. Does anyone know why it would be there? Does it look like a snippit of any script you know of, because I did not write the code!
