My question is regarding the legal aspect of including free open source 3rd party libraries in my commercial software. As an example, I have used the c# library MySqlBackup.NET to be able to backup and restore a MySQL database from my C# app. The license page of the 3rd party library website states:
"Anyone is free to copy, modify, publish, use, compile, sell, or distribute this software, either in source code form or as a compiled binary, for any purpose, commercial or non-commercial, and by any means."
The rest of the license can be read here. Is it correct that I must have a reference of this is my own Terms and Conditions? If so, what is the correct way to go about this? Perhaps as an Appendix at the end?
