## Description

OpenAPI Generator CLI is a command-line utility designed to automate the creation of API artifacts from specification files. It functions as a tool for generating client libraries, server stubs, and documentation, enabling developers to produce consistent boilerplate code and reference materials across various programming languages.

The project provides a wrapper that manages the lifecycle of a Java-based execution engine, which performs the actual code synthesis using logic-less templates. To ensure reproducible results and avoid dependency conflicts on the host system, the tool supports version-controlled engine management and containerized execution environments.

Users can define project-specific generation rules through persistent configuration files, which automate repetitive tasks and maintain consistency across different development environments. The toolset covers the full scope of API artifact production, from initial server skeleton creation to the generation of integrated client software development kits.
