+    (description "OpenGLRaw is a raw Haskell binding for the OpenGL 4.5
+graphics system and lots of OpenGL extensions.  It is basically a 1:1 mapping
+of OpenGL's C API, intended as a basis for a nicer interface.  OpenGLRaw
+offers access to all necessary functions, tokens and types plus a general
+facility for loading extension entries.  The module hierarchy closely mirrors
+the naming structure of the OpenGL extensions, making it easy to find the
+right module to import.  All API entries are loaded dynamically, so no special
+C header files are needed for building this package.  If an API entry is not
+found at runtime, a userError is thrown.")
