# This makefile lets you MANUALLY create a set of images and the corresponding
# DEFAUL.yaml file for a particular platform. It should NOT be run
# automatically, but only when the master images have changed following review
# by the localization team. Additionally, it needs to be run outside of the
# chroot, since it uses ImageMagick to transform the master images, and
# ImageMagick is much to complex to bother installing into the chroot just for
# this occasional need.
