# This script is an alpha version.
#
# The goal is to get a list of messages not yet localised in a
# languageXX.php file using the language.php file as reference.
#
# Usage:
# php DiffLanguage.php
#
# Enter the language code following "Language" of the LanguageXX.php
# you want to check. If using linux you might need to follow case aka
# Zh and not zh.
#
# The script then print a list of wgAllMessagesXX keys that aren't
# localised, a percentage of messages correctly localised and the
# number of messages to be translated.
#
#
# Known bugs:
# - File paths are hardcoded
# - Can't check your configured language.(says nothing is localised)
#
