  ```python
        /Users/mgrover/miniforge3/envs/open-science-rockies-dev/lib/python3.9/site-packages/setuptools/command/install.py:34: SetuptoolsDeprecationWarning: setup.py install is deprecated. Use build and pip and other standards-based tools.
          warnings.warn(
  ```
  
  We should move to a setup.cfg file for setuptools, similar to other projects.
