This one was actually pretty easy. There are links in the script that go to the perl manual page on that specific function (the links are the functions, click on them and you will go to the manual page), and thats very useful for these mission, kudos to the developers for making it easier.
I have never written anything in perl, and never looked at the manual pages before extended basic 8, and still solved this one in about 4 minutes (the time it took me to find what i needed to know, granted I already knew what i was looking for)
Yeah so all you need is a basic understanding or reading/writing to files, and follow the links in the script to understand what the functions that are being used do.
