+    """The GL Vendor-Neutral Dispatch library
+
+    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."""
