Engine

The Engine module manages the execution environment of Nelson itself.

It provides mechanisms to handle program startup and shutdown behavior, command-line integration, and runtime modes.

This includes support for user-defined initialization and termination scripts, platform-specific system requirements, and interpreter directives for cross-platform script execution.

It serves as the core interface between Nelson and the underlying operating system, ensuring flexible configuration and smooth control over how the software is launched and operated.
