## Description

This project provides a server-side language runtime and a standardized Docker image for deploying applications across different operating systems. It functions as an execution environment for generating dynamic HTML, JSON, and XML content, while also serving as a command line interface for automation scripts and background jobs.

The runtime is designed for extensibility through a C-based extension architecture, allowing the loading of custom modules for specialized functionality. It supports multiple server application interfaces, including a FastCGI web interface for high-performance communication with web servers and a built-in web server for hosting pages without external installations.

The capability surface covers a wide range of systems programming and web development tasks. These include database integration for SQL and non-relational engines, network protocol communication via HTTP and SOAP, and security primitives for password hashing and symmetric encryption. Additionally, the runtime provides tools for XML processing, multibyte string handling, and arbitrary precision mathematics.

The project is packaged as a layered container image to ensure consistent execution across various hosting environments.
