openscenario-rs 0.3.1

//! OpenSCENARIO Universal Parser Tool
//!
//! This command-line tool parses any OpenSCENARIO file type and demonstrates the complete
//! parsing system for production use cases.
//!
//! ## Features
//! - Command-line interface for scenario file processing
//! - Support for scenarios, parameter variations, and catalogs
//! - Parameter variation analysis with scenario file import
//! - Complete catalog reference resolution with parameter substitution
//! - Automatic catalog discovery and loading
//! - File path resolution (relative paths made absolute relative to scenario location)
//! - Expression resolution (${...} expressions evaluated with parameter context)
//! - Clean output generation with resolved entities
//! - Comprehensive logging and progress reporting
//!
//! ## Usage
//! ```bash
//! cargo run --example parse -- path/to/scenario.xosc
//! cargo run --example parse -- path/to/variation.xosc
//! ```
//!
//! ## Output
//! - Creates an 'output' directory if it doesn't exist
//! - Generates a resolved scenario file: `output/resolved_scenario.xosc`
//! - For parameter variations: also parses and displays the referenced scenario
//! - Logs all resolution activities and statistics
