Many tools are not in the conda package, and documentation (sometimes fairly
limited) is available at the beginning of each script.

**Note**: as of Sep 2025, [@xylar](https://github.com/xylar/) who has been the main maintainer of the conda package will no longer be working on the project. As a result updates to the `mpas_tools` conda package may be limited after that date.
