${bold}Build Environment Simple Reference:${normal}
	${bldblu}make mrproper${normal}			- cleans ALL build information, including .config
	${bldblu}make clean${normal}			- cleans last build output, saves .config
	${bldblu}make $defconfig${normal}	- copies the defconfig to .config
	${bldblu}make menuconfig${normal}			- spawns the .config editor
	${bldblu}make zImage${normal}			- builds the kernel, outputs to ./arch/arm/boot/zImage

${bold}Extra Useful Commands:${normal}
	${bldblu}ctop${normal}		- change the directory to the top of the kernel tree (`pwd`)
	${bldblu}cmsm${normal}		- change to the arch/arm/mach-msm directory
	${bldblu}nconfig${normal}		- nano the .config file (`pwd`/.config)
