1//! Package metadata parsing and runtime loading.
2//!
3//! This module provides:
4//!
5//! - **DESCRIPTION parser** (`description.rs`): Debian Control File format for
6//! package metadata (name, version, dependencies).
7//!
8//! - **NAMESPACE parser** (`namespace.rs`): directive-based DSL for exports,
9//! imports, and S3 method registrations.
10//!
11//! - **Rd parser** (`rd.rs`): LaTeX-like format used in package `man/`
12//! directories for `help()` lookup and example extraction.
13//!
14//! - **Package loader** (`loader.rs`): runtime package loading — discovers
15//! packages on `.libPaths()`, creates namespace/exports environments, sources
16//! R files, and manages the search path.
