Simplify your setup.py

setupmeta is a Python library designed to significantly reduce boilerplate in `setup.py` files by automatically inferring project metadata from common project conventions. It extracts information like long description from `README.rst`/`README.md`, version from `__version__.py` or Git tags, and dependencies from `requirements.txt`. It encourages a DRY (Don't Repeat Yourself) approach to Python packaging. The current version is 3.9.0, and it is actively maintained with a regular release cadence.
