# Tool which tries to find outdated translations in the engine strings (*.txt) using hg blame.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# Strings which this tool lists MIGHT be outdated, so you might want to re-translate them, if needed.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
