Acknowledgements

This library builds upon work from two upstream projects:

• jetelain/bis-file-formats — The fork this repository was originally derived from, containing the most up-to-date format parsers.
• Braini01/bis-file-formats — The original upstream project that laid the foundation for many of the format implementations.
