extract-json

#! /bin/bash

# Extract strings from a list of JSON files.
#
# This script will extract strings from all JSON files in the directory
# passed as first argument. The second argument is the destination
# directory for the extracted message file.
#
# This script uses createjsoncontext to generate the actual message file
# from the JSON file.
#
# This script is based on handle_json_files.sh from KDE's translation
# scripts.
