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10 # that may be missing/out of date.
