#
# Automagically generate localized KTurtle logo code.
#
# Usage: ./i18n_examples.pl logokeywords.YOURLANGCODE.xml
# 
# e.g.: 
# $./i18n_examples.pl logokeywords.es.xml
#
# arrow.logo -> arrow.es.LOGO
# canvascolors.logo -> canvascolors.es.LOGO
# curly.logo -> curly.es.LOGO
#
# NOTES:
# - You'll need logokeywords.YOURLANGCODE.xml under kturtle/scripts
# - Commented lines, variable names, and strings like
# "What's your name?" must be translated by hand.
# - You might want to rename the resulting files to something 
# into your own language e.g. arrow.es.LOGO to flecha.LOGO
# - Please, if the script is not working for you report it to
# KDE-Edu mailing list.

The translation of KTurtle examples is almost DONE...
You will need to translate the following by hand:
1) Commented lines,
2) Variable names (if any of them is named in english or represents a reserved word in your language),
3) Strings like "What's your name?"
4) File names 

Thanks a lot!
