//! ## Quick start (library)
//!
//! ```rust,no_run
//! use rbt::{RbtProjectConfig, TransformationEngine};
//! # async fn demo() -> anyhow::Result<()> {
//! let project = std::path::Path::new(".");
//! let config = RbtProjectConfig::load(project)?;
//! let dag = config.build_dag(project, None)?;
//! let engine = TransformationEngine::new();
//! let _summary = engine.execute_dag(&dag, project, "./target/output").await?;
//! # Ok(())
