A Python CLI tool for searching, downloading, and organizing doujinshi (self-published manga) from configurable mirror sites. The architecture uses a plugin system defined via abstract base classes (BaseParser, BaseModel, BaseSerializer, BasePlugin) and discovered through Python entry points, allowing support for multiple sites (e.g., nhentai) without modifying the core code. The core package handles CLI argument parsing, asynchronous image downloading via httpx/asyncio with retry and proxy support, export to CBZ/PDF/ZIP, generation of HTML viewers for local browsing, and SQLite-based download history tracking. The codebase is well-structured with clear separation between core utilities and plugin-specific logic, though it contains duplicated viewer template files that indicate incomplete cleanup.
