# Example usage
if __name__ == "__main__":
    reasoning_engine = ReasoningEngine()
    
    # Adding some facts to the knowledge base
    reasoning_engine.add_fact("temperature", "If temperature is above 30, it's hot.")
    reasoning_engine.add_fact("weather", "If weather is sunny and warm, expect clear skies.")
    
    print(reasoning_engine.derive_conclusion(["temperature is above 30", "weather is sunny"]))
```

This example creates a basic reasoning engine capable of adding facts to a knowledge base and deriving simple conclusions based on the given facts.
