# Tool which tries to find outdated translations in the engine strings (*.txt) using hg blame.
# Note this is only a heuristic; the output might not be 100% accurate.
# Strings which this tool lists MIGHT be outdated, so you might want to re-translate them, if needed.
# Run this in the tools/ directory.

# SYNTAX:
#
# ./find_outdated_engine_translations.sh <LANGUAGE>
#
# <LANGUAGE>: Language code of the language to check
