4//! Parser for Autotools configure scripts.
5//!
6//! Extracts basic package metadata from Autotools configure files by using
7//! the parent directory name as the package name.
8//!
9//! # Supported Formats
10//! - configure (Autotools configure script)
11//! - configure.ac (Autoconf input file)
12//!
13//! # Key Features
14//! - Lightweight detection based on parent directory name
15//! - No file content parsing required
16//!
17//! # Implementation Notes
18//! - This parser does NOT read file contents, only extracts parent directory name
19//! - configure.in is NOT supported (deprecated legacy format)
20//! - Returns minimal PackageData with only package_type and name fields
