Acknowledgements

This project was made possible thanks to the inspiration and information provided by the following projects:

• psf_utils – A well-established PSF parser built with PLY, helpful for understanding the PSF ASCII format.
• libpsf – The original reverse-engineering project for the binary PSF format, which served as the primary source for this implementation.

Special thanks to the maintainers and contributors of these projects for their open source work.
