This is built-in to pyproject.toml https://packaging.python.org/en/latest/guides/writing-pyproj...

supported by uv for example https://docs.astral.sh/uv/concepts/projects/init/#packaged-a... Benefit is you can just type the command, no need to prepend pyqwe or anything.

See also justfile for a non-python specific tool https://github.com/casey/just Which I just learned can be installed with Python! https://pypi.org/project/rust-just/

pyqwe isn't a build tool, it's more like just but designed for the pyproject.toml file. The idea was to keep it simple and close to Python.
