#

# 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.py <input_dir> <output_dir>

#

# Script reads S60 loc zip files from <input_dir> directory and writes

# java loc zip files and "resources.jar" to <output_dir> directory.

#

# This script uses external "jar" command for handling zip files and

# thus is not optimized for speed.
