# Script to check all engine locale files (XX.txt)

# HOW TO USE:

# - Run this script in the tools/ directory.

# Result: All problems and missing translations in .txt files will be reported

# SYNTAX:

#

#     ./check_engine_locale_files.sh [file_to_check [show_untranslated]]

#

# Optional parameters:

#

# * file_to_check: Add this if you want to check a single file. Use the special value ALL to check all files.

# * show_untranslated: Set to 0 if you want to hide the list of untranslated files, set to 1 otherwise
