Core

The Core module provides the fundamental building blocks of the Nelson environment.

It includes essential services for program execution, environment management, and system interaction.

Through this module, users can evaluate code dynamically, manage execution flow, query program state, and access key system information such as versioning, configuration, and licensing.

It also offers basic utilities for file identification, checksums, and terminal capabilities.

Together, these features form the foundation upon which all other modules and user-level functionality in Nelson are built.
