"""
This script helps track the translation status of the documentation
in different locales, e.g., zh_CN. More specially, it uses `git log`
commit to find the latest english commit from the translation commit
(order by author date) and the latest english commits from HEAD. If
differences occur, report the file and commits that need to be updated.
The usage is as follows:
- ./scripts/checktransupdate.py -l zh_CN
This will print all the files that need to be updated in the zh_CN locale.
- ./scripts/checktransupdate.py Documentation/translations/zh_CN/dev-tools/testing-overview.rst
This will only print the status of the specified file.
The output is something like:
Documentation/translations/zh_CN/dev-tools/testing-overview.rst (1 commits)
commit 42fb9cfd5b18 ("Documentation: dev-tools: Add link to RV docs")
