May not require any wrapping, if so then this ticket is just for tracking. Otherwise, adjust SP.
Wrap meas_base with pybind11
Wrap coadd_utils with pybind11
port jointcal to pybind11
Wrap obs_test with pybind11
Wrap obs_base (was daf_butlerUtils) with pybind11
Wrap afw using pybind11
pipe_base contains no C++ code but relies on a few C++ objects
The # of story points is an upper limit.
It works with afw and obs_test as presently wrapped. I have no reason to suspect this will change, but will file a new ticket if something breaks.
