SUMMARY="Low-level replacement for pep517"
DESCRIPTION="This is a low-level library for calling build-backends in 'pyproject.toml'-based \
project. It provides the basic functionality to help write tooling that generates distribution files \
from Python projects.

If you want a tool that builds Python packages, you’ll want to use https://github.com/pypa/build \
instead. This is an underlying piece for pip, build and other “build frontends” use to call \
“build backends” within them.

Note: The 'pep517' project has been replaced by this project (low level) and the 'build' project \
(high level)."
