Yes, the script before this one (using Tie) looked exactly like this, and that is still what I use now after the new version failed to do anything useful in reasonable time, but I was hoping that maybe I could optimize this code somehow - using Tie makes things so easy - just like looping through an array!

Well, I am not totally out of luck, as I am reading line by line anyways, and not much change would be required to translate it into a direct file IO .. but in case someone comes across a light bulb in their vicinity, keep this node updated!
