I gave this a neutral rating. I downloaded it to see what it was, and if there was any chance at all that it could be made to work in a Linux environment. Well, as of the end of 2015 there appear to be no Linux tools able to handle a PDF with the extensions that this file uses.
So, if you live in the Windows (and maybe the Mac) world, then this might be a useful aid for you. If you're in the Linux world, its a no-go.
