Acknowledgements

This project is based on a template I downloaded some time ago. Unfortunately, I have not been able to identify the original author—if you are or know the creator, please let me know so I can give proper credit.

I have simplified the code, use more standard LaTeX, improved typesetting aesthetics, added booktabs support, and integrated Spanish translation with babel.
