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)
