"""
PHP Mess Detector (PHPMD) Parser - PHP code quality and complexity analysis.

PHPMD is a spin-off project from PHP Depend and aims to be a fast and
extensible static analyzer for finding problematic patterns in PHP source code.

PHPMD provides:
- Code smell detection (naming, size, complexity)
- Unused code detection
- Code rule customization
- Multiple output formats (XML, HTML, text, JSON)
- Custom ruleset creation support
