# This script takes a bunch of world image files and combines them
# into one large image. This should be run from the directory
# where all the images are.
# Note that this takes a while to run. Probably pretty proportional
# to the size of the target image.
# This is somewhat hacked for my usage - it presumes you run this
# from the top level of the maps directory (eg, contains world, scorn,
# etc directories). This is smart enough to regen the image files
# that may be missing/out of date.
