Linux: AutoRAR & PAR2 script

So...i was sitting and drinking iced tea with a slice of a lemon and I remembered that from time to time we have here topics asking about semiautomatic creation of rars\pars for a bunch of files at once.

Well, you know we have some windows based tools like autorarpar, for instance, old preusenet or jbinup(that works on linux as well but it cant autorarpar lots of files in automatic mode, creating rars based on the files names, you need to specify everything manually)

So a friend of mine wrote this script, Feel free to test it, edit it according to your preferences, discuss etc
