Framework

All of the Packages and Modules that are not in the components (mesh, ocean and seaice) belong to the polaris framework. Some of these modules and packages are used by the Command-line interface, while others are meant to be called within tasks and steps to simplify tasks like adding input and output files, downloading data sets, building up config files, yaml files, namelists and streams files, setting up and running the E3SM component, and verifying the output by comparing steps with one another or against a baseline.

The framework is organized to separate tasks and shared framework code. Tasks for each component are located in polaris.tasks.<component>, while shared framework code (e.g., config files, YAML files, utilities) is located in polaris.<component>. This separation ensures clarity and avoids circular dependencies.
