pyproject.toml

The build-system section can also look something like:

[build-system]
requires = ["uv_build>=0.9.7,<0.10.0"]
build-backend = "uv_build"

There are a couple different ways to build the project. You can do it the traditional way with "setuptools" and "wheel" or use "uv_build" which is a faster but python only build method. If your project is pure python and you initialize the project with the uv package manager, then uv will add it's own build package as the method by which it builds the project. This should be fine even if someone doesn't use uv for package management because, as I understand it, the build-system requirements are installed in some temp environment when it comes time to build the project, and one method is just using one set of packages to build while the other method is just using a different package.
