/** This piece of crap reads several zRIF keys stored in a zrif.txt file and try, with each one until EOF, executing the command line below into Motoharu-Gosuto's psvpfstools.
 *
 * psvpfsparser.exe -i PCSXXXXXX -o PCSXXXXXX_ctm -z <zrif> -f http://cma.henkaku.xyz
 *
 * You DEFINITELY should check his other collaborations for the PS Vita scene on his GitHub page: https://github.com/motoharu-gosuto
 *
 * I'm still in learning stage of programming, so this code is definitely not surprising for anyone who studies it, but I believe everyone should start collaborating for the scene somewhere. I got inspired to do this after having some little problems using an old tutorial on r/VitaPiracy about how to install NPS themes on non-Ensou hacked PS Vita. I'm not blaming the tutorial, my problem was that I downloaded too many themes without ordenating the zRIF keys needed for decrypt, and wasted a couple of time installing them. By the way, if you're interested, you should check the post I'm talking about: https://old.reddit.com/r/VitaPiracy/comments/987jyq/tutorial_installing_nps_themes_on_367368_without/
 * To be honest, I don't know who besides me would be that idiot to get a bunch of themes and a lot of zRIF keys without ordenation, but if you do, you can spare your time by using this script without testing one-by-one yourself.
 *
 * Usage:
 * After compilation of this source code, drag the PCSXXXXXX theme folder into the .exe.
 * Be sure that both the folder, the zrif.txt and psvpfsparser.exe are in the same directory.
