"Forge is an OpenGL interop library that can be used with ArrayFire or any other application using CUDA or
OpenCL compute backend. The goal of **Forge** is to provide high performance OpenGL visualizations
for C/C++ applications that use CUDA/OpenCL. Forge uses OpenGL >=3.3 forward compatible contexts, so
please make sure you have capable hardware before trying it out.")
