# 4D Project Cleaner

Remove generated files and caches from a 4D project.

## Usage

The script auto-detects the project root by finding the `.4DProject` file.

```bash
# From anywhere inside the project
python scripts/clean.py

# Or specify a path
python scripts/clean.py /path/to/4d-project
```

The script reports what was removed.
