+/* This code is very useful, if you are cracking software and you need
+to share your cracks without whole binary (because of size or copyright).
+This is simple way to patch binaries at users home.
+Warning: You need to know some things about PE (probably) architecture to use this.
+But there is still some automatic computing with addreses,
+so you have to know only bit about yours binary...
