### Custom Content Extractor

```java
public class CustomExtractor extends AbstractExtractor {
    @Override
    public ExtractData getText(final InputStream inputStream, final Map<String, String> params) {
        // Custom extraction logic
        ExtractData extractData = new ExtractData();
        // ... implementation
        return extractData;
    }
}

Esse arquivo `requirements.txt` será usado com `pip` mais tarde no **próximo estágio**.

Na imagem final do contêiner, **somente o estágio final** é preservado. Os estágios anteriores serão descartados.
