Hey everyone, I was looking for a program to make graphs out of the civscore.log file the other day and all I found was some php I didn't want to use and an ancient perl script that didn't seem to do anything. So I cooked one up myself real quick, it's still very basic- I didn't add command line switches or anything yet, but as long as you have a perl interpreter and gnuplot installed it'll do the trick. I've attached the program and a png to demonstrate.
The code can also be found at http://code.google.com/p/civscore-tools/ if you want to keep up with it or contribute. There is also a copy of my civscore.log file(too big to attach)
