OpenGL Overload (GLO) is new project I am working on.
I have been thinking of replacing GLEW for a while. Unfornunatly, GLEW isn't well maintained and lack of some fonctionnalities such project could provide.
The goal of GLO is first to provide a loading of the OpenGL implementation on Windows (probably OpenGL 3.2 core for the moment). The second point is to provide some kind of debugging fonctionnalies. When enabled, each OpenGL function will be automatically checked and return a message in case of any issue. Finally, a third objective is to provide a basic C++ wrapper.
I expect to release a first version as soon as it can replace GLEW in the OpenGL 3 Samples Pack.
