It also comes with this "Plain English Copyright Notice" in COPYING.PLAIN:
Plain English Copyright Notice This file is not intended to be the actual License. The reason this file exists is that we here are programmers and engineers. We aren't lawyers. We provide licenses that we THINK say the right things, but we have our own intentions at heart. This is a plain-english explanation of what those intentions are, and if you follow them you will be within the "spirit" of the license. The intent is for us to enjoy writing software that is useful to us (the AUTHORS) and allow others to use it freely and also benefit from the work we put into making it. We don't want to restrict others using it. They should not *HAVE* to make the source code of the applications they write that simply link to these libraries (be that statically or dynamically), or for them to be limited as to what license they choose to use (be it open, closed or anything else). But we would like to know you are using these libraries. We simply would like to know that it has been useful to someone. This is why we ask for acknowledgement of some sort. You can do what you want with the source of this software - it doesn't matter. We still have it here for ourselves and it is open and free to use and download and play with. It can't be taken away. We don't really mind what you do with the source to your software. We would simply like to know that you are using it - especially if it makes it to a commerical product. If you simply e-mail all the AUTHORS (see COPYING and AUTHORS files) telling us, and then make sure you include a paragraph or page in the manual for the product with the copyright notice and state that you used this software, we will be very happy. If you want to contribute back modifications and fixes you may have made we will welcome those too with open arms (generally). If you want help with changes needed, ports needed or features to be added, arrangements can be easily made with some dialogue. Carsten Haitzler <firstname.lastname@example.org>
