"""The GL Vendor-Neutral Dispatch library (Frontend Dummy Package)
libglvnd is a vendor-neutral dispatch layer for arbitrating OpenGL API
calls between multiple vendors. It allows multiple drivers from different
vendors to coexist on the same filesystem, and determines which vendor to
dispatch each API call to at runtime.
Both GLX and EGL are supported, in any combination with OpenGL and OpenGL
ES."""
