Some distributed binaries of this project optionally include the PyMuPDF library, which is licensed under **AGPL3.0orlater**. 
Any binary that incorporates PyMuPDF is therefore distributed under **AGPL3.0orlater**. 
Binaries that include the `pypdf` library and/or the `pdfium` library as the PDF analysis engine(s), and do not include PyMuPDF, are distributed under the **MIT License**.

For AGPL-licensed binaries, the complete corresponding source code must be made available to anyone who possesses a copy, upon request. 
This obligation applies only to recipients of those binaries, and hosting the source code in GitHub Releases satisfies this requirement.
Source code for each released version is available in the `pdflinkcheckVERSION.tar.gz` files on the projects GitHub Releases page.

The **source code of pdflinkcheck itself** remains permissively licensed under the **MIT License**. Only a distributed binary (or a publicly served web app) becomes AGPL-licensed when PyMuPDF is included.

Please inspect the terms of the PyMuPDF and the associated **AGPL3.0orlater** license.
