Available Commands:
	help:	This help text
	info:	Show a list of available target profiles
	clean:	Remove images and temporary build files
	image:	Build an image (see below for more information).

Building images:
	By default 'make image' will create an image with the default
	target profile and package set. You can use the following parameters
	to change that:

	make image PROFILE="<profilename>" # override the default target profile
	make image PACKAGES="<pkg1> [<pkg2> [<pkg3> ...]]" # include extra packages
	make image FILES="<path>" # include extra files from <path>
	make image BIN_DIR="<path>" # alternative output directory for the images
	make image EXTRA_IMAGE_NAME="<string>" # Add this to the output image filename (sanitized)
	make image DISABLED_SERVICES="<svc1> [<svc2> [<svc3> ..]]" # Which services in /etc/init.d/ should be disabled
	make image ADD_LOCAL_KEY=1 # store locally generated signing key in built images
	make image ROOTFS_PARTSIZE="<size>" # override the default rootfs partition size in MegaBytes

Print manifest:
	List "all" packages which get installed into the image.
	You can use the following parameters:

	make manifest PROFILE="<profilename>" # override the default target profile
	make manifest PACKAGES="<pkg1> [<pkg2> [<pkg3> ...]]" # include extra packages
	make manifest STRIP_ABI=1 # remove ABI version from printed package names
