## Usage Example

### 1. Define CLI in RDF

```turtle
@prefix cli: <http://ggen.dev/ontology/cli#> .

:MyApp a cli:CLIApplication ;
    cli:commandName "myapp" ;
    cli:hasCommand :ProcessCommand .

:ProcessCommand a cli:Command ;
    cli:commandName "process" ;
    cli:hasArgument :InputArg ;
    cli:hasOption :OutputOpt .

:InputArg a cli:Argument ;
    cli:argumentName "input" ;
    cli:argumentType cli:PathType ;
    cli:argumentRequired true .

:OutputOpt a cli:Option ;
    cli:optionLong "output" ;
    cli:optionShort "o" ;
    cli:optionType cli:PathType .
```

### 2. Generate CLI

```bash
ggen generate cli-application-template \
  --input spec.ttl \
  --output myapp-rs \
  --language rust
```

### 3. Build and Run

```bash
cd myapp-rs
cargo build --release
./target/release/myapp process input.txt --output result.txt
```
