description        OpenGL Extension Wrangler Library
long_description   The OpenGL Extension Wrangler Library (GLEW) is a \
                   cross-platform C/C++ extension loading library. GLEW \
                   provides efficient run-time mechanisms for determining \
                   which OpenGL extensions are supported on the target \
                   platform. OpenGL core and extension functionality is \
                   exposed in a single header file.
