Nope, I really don't want to rob from you the joy of discovering things by yourself.
The script is pretty brief and self-explanatory. Try it out on a sample data, comment out different portions and see how the result changes, check the syntax from the man pages or the online gawk manual ("http://www.gnu.org/software/gawk/manual/gawk.html"), put in some effort and soon enough, you'll figure it out yourself. And then you'll *know* it real good.
