# Creates the sample images for Quack from originals.
# This script is only relevant if the caller has access
# to the original scanned files. These are not stored
# with the Quack code as their cumulative size is 34MB.
# Contact Toke Eskildsen - te@statsbiblioteket.dk if
# the originals are of interest.
