+	  Waffle is a cross-platform library that allows one to defer
+	  selection of an OpenGL API and of 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.
+
+	  Waffle's immediate goal is to enable Piglit [1] to test
+	  multiple OpenGL flavors in a cross-platform way, and to allow
+	  each Piglit test to choose its OpenGL API and window system
+	  at runtime. A future goal is to enable the ability to record
+	  (with another tool such APITrace [2]) an application's OpenGL
+	  calls on one operating system or window system, and then
+	  replay that trace on a different system.
+
