Quick reference: setuptools

Requirements

Ideal

• requirements.txt files present in your project

Minimum

• setup.py files present in your project.

Unfortunately, we fail to parse many valid setup.py files. In general, we recommend the use of requirements.txt files for better analysis.

Project discovery

Directories containing setup.py files or requirements.txt-like files (e.g., req-dev.txt, test-requires.txt are valid -- or any filename matching the regex .*req.*\.txt) are treated as setuptools projects.
