SUMMARY = "A C library for selecting an OpenGL API and window system at runtime"
DESCRIPTION = "A cross-platform C library that allows one to defer selection \
of an OpenGL API and window system until runtime. For example, on Linux, Waffle \
enables an application to select X11/EGL with an OpenGL 3.3 core profile, \
Wayland with OpenGL ES2, and other window system / API combinations."
