# This script automates the generation of resources.py for OpenLP saving a
# backup of the old resources, inserting the coding and copyright header and
# conforming it to the project coding standards.
#
# To make use of the script:
# 1 - Add the new image files in resources/images/
# 2 - Modify resources/images/openlp-2.qrc as appropriate
# 3 - run sh scripts/generate_resources.sh
#
# Once you have confirmed the resources are correctly modified to an updated,
# working state you may optionally remove openlp/core/resources.py.old
