-## Acknowledgements
-This crate reuses/builds upon two significant libraries:
-- [ttf-parser](https://github.com/RazrFalcon/ttf-parser): Large parts of the code have been copied and adapted
-from that crate, including but not limited to the reader/writer, parsing logic of certain tables as well as a large
-part of the CFF parsing logic. This crate is dual-licensed under MIT/Apache.
-- [fonttools](https://github.com/fonttools/fonttools): The logic for decompiling charstrings has been adapted from
-that library. It is licensed under the MIT license.
