## Use Cases

### 1. Verify Installation

Check that Graphman is properly installed and accessible:

```bash
graphman version
```

### 2. Check Schema Compatibility

Verify which schema versions are supported before working with a specific Gateway version:

```bash
graphman version
```

### 3. Troubleshooting

Include version information when reporting issues or seeking support:

```bash
graphman version > version-info.txt
```

### 4. Automation Scripts

Verify the Graphman version in automation scripts before executing operations:

```bash
#!/bin/bash
graphman version
# ... rest of automation script
```
