Brief overview of the following glbinding tools:
The tools are also available pre-compiled, e.g., as Windows archive glbinding-2.0.0-msvc2015-x64-tools.zip or Ubuntu package:
sudo apt-add-repository ppa:cginternals/ppa
sudo apt-get update
sudo apt-get install libglbinding-tools
contexts requests OpenGL contexts for all valid versions and lists the resulting versions. This helps to gather intel on context creation on various system setup's (operating systems, GPUs, and OpenGL drivers). Feel free to post your results to complete the Context Creation Cheat Sheet. Example output on a Windows 8.1:
test: requesting all context configurations ...
