SCRIPT_DESCRIPTION = '''
usage: ./easy_diff.py language/document path
Show the difference between a language document and an English document.
This script is based on the assumption that documents in other languages are fully synchronized with the en document at a commit.
For example:
Execute:
./easy_diff.py --no-pager zh/data_types
Output:
Need translate document:~/ClickHouse/docs/en/data_types/uuid.md
Need link document:~/ClickHouse/docs/en/data_types/decimal.md to ~/ClickHouse/docs/zh/data_types/decimal.md
