| Installation | The project recommends installing the cpplint package from PyPI and documents installation as a uv tool. | The official quickstart installs Flake8 with python -m pip install flake8 and recommends invoking the interpreter-specific module when multiple Python versions are installed. |
| Purpose | Cpplint is a command-line tool that checks C/C++ files for style issues according to Google’s C++ style guide. | Flake8 combines pycodestyle, pyflakes, McCabe, and third-party plugins to check Python code style and quality. |
| Python requirement | The PyPI package requires Python 3.9 or later. | The current PyPI release requires Python 3.10 or newer. |
