This is a really simple app that just restarts your console. When used with things like the Aroma ftp plugin it's surprisingly convenient though :P
To build this make sure you have devkitPro, devkitPPC and wut installed via the dkp-pacman package manager. Then just run make in the same directory as the Makefile and use the resulting wuhb.
Special thanks to Ingunar for the icons!
