  37 Building images:
  38         By default 'make image' will create an image with the default
  39         target profile and package set. You can use the following parameters
  40         to change that:
  41
  42         make image PROFILE="<profilename>" # override the default target profile
  43         make image PACKAGES="<pkg1> [<pkg2> [<pkg3> ...]]" # include extra packages
  44         make image FILES="<path>" # include extra files from <path>
  45         make image BIN_DIR="<path>" # alternative output directory for the images
  46         make image EXTRA_IMAGE_NAME="<string>" # Add this to the output image filename (sanitized)
