### Auto-Generated Files

Never edit these files manually (marked with `@author FreeGen`):
- `FessLabels.java`
- `FessMessages.java`

Always regenerate them using `mvn dbflute:freegen`

## Complete Example: Adding Swedish (sv)

```bash
# 1. Navigate to resources directory
cd src/main/resources

# 2. Copy base files
cp fess_label_en.properties fess_label_sv.properties
