+Install devkitpro's devkitARM, the devkitarm-rules and devkitarm-crtls
+files, and set DEVKITPRO to the path where you installed it.
+After that, arm-none-eabi* should resolve to the tools in this kit
+with the proper files in place, not the one in the system.
+
+If all goes well:
+	make && vba *.gba
+
+Have fun!
