async fn main() -> Result<(), Box<dyn std::error::Error>> {
    // Initialize Grim Reaper
    let grim = Grim::new(Config::default())?;
    
    // Quick backup
    grim.backup("/home/user/data").await?;
    
    // Start monitoring

- **WARNING** - Non-critical issues
- **DEBUG** - Detailed debugging information

## Development

### Adding New Commands

1. **Add command to CLI structure** in `src/main.rs`:
   ```rust
   #[derive(Subcommand)]
   enum Commands {
       // ... existing commands ...
       
       /// New command description
       NewCommand {
           /// Option description
           #[arg(short, long)]
           option: Option<String>,
       },
   }
   ```

2. **Add handler function**:
   ```rust
   async fn handle_new_command(option: Option<&str>) -> Result<()> {
       info!("Handling new command with option: {:?}", option);
       // Implementation here
       Ok(())
   }
   ```

3. **Add to main match statement**:
   ```rust
   match &cli.command {
       // ... existing matches ...
       Commands::NewCommand { option } => {
           handle_new_command(option.as_deref()).await?;
       }
   }
   ```

### Testing

```bash
# Run all tests
cargo test

# Run specific test
cargo test test_name

# Run tests with output
cargo test -- --nocapture

# Run benchmarks
cargo bench
```

### Code Quality

```bash
# Run Clippy
cargo clippy

# Format code
cargo fmt

# Check formatting
cargo fmt -- --check
```

## Performance

### Build Optimizations

The release profile includes several optimizations:

```toml
[profile.release]
opt-level = 3        # Maximum optimization
lto = true          # Link-time optimization
codegen-units = 1   # Single codegen unit
panic = "abort"     # Abort on panic (smaller binary)
```

### Binary Size

- **Release build**: ~1.2MB
- **Debug build**: ~15MB
- **Stripped release**: ~800KB

### Memory Usage

- **Idle**: ~2MB
- **Active backup**: ~10-50MB (depending on file size)
- **Peak**: ~100MB (large operations)

## Security Considerations

### Input Validation

- All user inputs are validated before processing
- File paths are sanitized to prevent directory traversal
- Network requests use HTTPS by default

### Error Handling

- Sensitive information is not logged
- Errors are handled gracefully without exposing internals
- Panic handling is configured for production

### Dependencies

- All dependencies are from trusted sources (crates.io)
- Regular security updates are applied
- No known vulnerabilities in current dependencies

## Troubleshooting

### Common Issues

#### Build Failures
