prompt_processing is a package in the LSST Science Pipelines.
prompt_processing contains code used for the Rubin Observatory Prompt Processing framework.
The design for the framework is described in DMTN-219 and DMTN-260.
At present, the package does not conform exactly to the layout or conventions of LSST stack packages.
In particular, the Python code does not use the lsst namespace, and the docs do not support Sphinx builds (even local ones).
