A build time package to simplify C/Cython extensions
Description
The extension-helpers package includes convenience helpers to assist with
building Python packages with compiled C/Cython extensions. It is developed
by the Astropy project but is intended to be general and usable by any
Python package.
This is not a traditional package in the sense that it is not intended to be
installed directly by users or developers. Instead, it is meant to be accessed
when the setup.py command is run and should be defined as a build-time
dependency in pyproject.toml files.
