## Key Features
- Tile generation with configurable parameters
- Automatic removal of empty tiles
- Geographic filtering (bbox and geometry-based)
- MetaTile support for efficient generation
- Legend image generation
- GetCapabilities document
- OpenLayers demo page
- Empty tile detection via hashing
- Cache synchronization
- Post-processing capabilities
## Legacy Support
Note: The following features are maintained for backward compatibility:
- Berkeley DB integration
- SQLite (MBTiles) support
