+//! # Rhailib Domain-Specific Language (DSL) Engine
+//!
+//! This module provides a comprehensive Domain-Specific Language implementation for the Rhai
+//! scripting engine, exposing business domain models and operations through a fluent,
+//! chainable API.
+//!
+//! ## Overview
+//!
+//! The DSL is organized into business domain modules, each providing Rhai-compatible
+//! functions for creating, manipulating, and persisting domain entities. All operations
+//! include proper authorization checks and type safety.
+//!
+//! ## Available Domains
+//!
+//! - **Business Operations** (`biz`): Companies, products, sales, shareholders
+//! - **Financial Models** (`finance`): Accounts, assets, marketplace operations
+//! - **Content Management** (`library`): Collections, images, PDFs, books, slideshows
+//! - **Workflow Management** (`flow`): Flows, steps, signature requirements
+//! - **Community Management** (`circle`): Circles, themes, membership
+//! - **Contact Management** (`contact`): Contact information and relationships
+//! - **Access Control** (`access`): Security and permissions
+//! - **Time Management** (`calendar`): Calendar and scheduling
+//! - **Core Utilities** (`core`): Comments and fundamental operations
+//! - **Generic Objects** (`object`): Generic object manipulation
+//!
+//! ## Usage Example
+//!
+//! ```rust
+//! use rhai::Engine;
+//! use crate::engine::register_dsl_modules;
+//!
+//! let mut engine = Engine::new();
+//! register_dsl_modules(&mut engine);
+//!
+//! // Now the engine can execute scripts like:
+//! // let company = new_company().name("Acme Corp").email("contact@acme.com");
+//! // let saved = save_company(company);
+//! ```

+/// Registers all DSL modules with the provided Rhai engine.
+///
+/// This function is the main entry point for integrating the rhailib DSL with a Rhai engine.
+/// It registers all business domain modules, making their functions available to Rhai scripts.
+///
+/// # Arguments
+///
+/// * `engine` - A mutable reference to the Rhai engine to register modules with
+///
+/// # Example
+///
+/// ```rust
+/// use rhai::Engine;
+/// use crate::engine::register_dsl_modules;
+///
+/// let mut engine = Engine::new();
+/// register_dsl_modules(&mut engine);
+///
+/// // Engine now has access to all DSL functions
+/// let result = engine.eval::<String>(r#"
+///     let company = new_company().name("Test Corp");
+///     company.name
+/// "#).unwrap();
+/// assert_eq!(result, "Test Corp");
+/// ```
+///
+/// # Registered Modules
+///
+/// This function registers the following domain modules:
+/// - Access control functions
+/// - Business operation functions (companies, products, sales, shareholders)
+/// - Calendar and scheduling functions
+/// - Circle and community management functions
+/// - Company management functions
+/// - Contact management functions
+/// - Core utility functions
+/// - Financial operation functions (accounts, assets, marketplace)
+/// - Workflow management functions (flows, steps, signatures)
+/// - Library and content management functions
+/// - Generic object manipulation functions (custom implementation)
