@edwardhartnett Looks good to me, thanks! Just curious what is the purpose of the pyproject.toml file? I'm unfamiliar with .toml files.

[edwardhartnett]

The pyproject.toml is the standard python way to pass options to all the build tools. Used to be each tool kept it's own config files, but that was a giant mess, so current best practice is to organize all tool settings in pyproject.toml. You will see more settings go into this file as we improve the python project.

@edwardhartnett After merging, I realized the pyproject.toml file is in the main level directory. Particularly for systems going to production, the main level directory should pretty sparse, filled mainly with various subdirectories (exec, fix, jobs, parm, scripts, sorc, ush, ...). Could it be tucked under the tests/ space, or is it critical to be within the main level directory?
