Generate a list of PAS images that are new since the previous survey of an image directory (like that done with pas_imlistgen).
% new_pas_images --help # The "--help" flag gives a longer explanation than seen here. Usage: new_pas_images list.IMAGES_previous list.IMAGES List0 N arg1 - initial image list (e.g. list.IMAGES from previous pas_imlistgen run) arg2 - current list (i.e. list.IMAGES from present pas_imlistgen run) arg3 - name of output image list with new images arg4 - run in debug mode (Y/N)This code does NOT just print out all images images in the arg2 file that are not present in the arg1 file. This routine is built for speed and hence assumes the simplest case where images added sequentially to a directory.
