Widgets 95 is derivative of GLUI. There is a vastly improved on version of GLUI that I (Mick P.) worked on as a contribution to the GLUI project located at https://github.com/mick-p1982/glui *************************************************************************** GLUI User Interface Toolkit --------------------------- (The ZLIB License) This software is provided 'as-is', without any express or implied warranty.

History of GLUI's License: -------------------------- Originally, GLUI was licensed under LGPL because Paul Rademacher just wanted something that was very permissive, and LGPL was the thing he had heard of. I discussed the license with Paul at SIGGRAPH 2006, where he told me the above, and also told me he was supportive of changing the license to one of the less restrictive open source licenses. So after contacting all the authors to get their OK, GLUI is now under the ZLIB license. Bill Baxter -- November 2007
