# Automagically gen. localized highlighting for KTurtle commands
#
# Usage:
# ./i18n_highlighting.pl logokeywords.YOURLANG.xml 
#
# E.g.
# ./i18n_highlighting.pl logokeywords.es.xml 
#
# NOTES:
# - You'll need logokeywords.YOURLANGCODE.xml under kturtle/scripts
# 
# - The script search for logokeywords.en_US.xml under ../data/
# and writes the resulting files under current directory
