#
# This script creates java specific loc zip files from S60 loc zip files
# and also creates a "resources.jar" file where all the java loc files
# are collected.
#
# Usage: extractJavaLocFiles_qt.py <input_dir> <output_dir> <resources_jar>
#
# Script reads S60 loc zip files from <input_dir> directory and writes
# "resources.jar" to <output_dir> directory.
#
# This script uses external "jar" command for handling zip files and
# thus is not optimized for speed.
