# this script converts the old face names to the new ones and checks whether
# the face can be found in the list of image filenames.
#
# First make a list of filenames:
#    find cf.schmorp.de/arch/ -name "*.png" -print > /tmp/face.filenames
#
# Second make a json file with the uuid->face mapping:
#    cd /var/crossfire/
#    grep_for_uuid_faces > /tmp/face.json
#
# Third call this to convert the facenames in the face.json:
#    json_conv_old_faces /tmp/face.json /tmp/face.filenames > /tmp/newface.json
#
# finished.
