+/*
+*  Name:
+*     grf3d.c
+
+*  Purpose:
+*     Implement the grf3D interface if no graphics system is available.
+
+*  Description:
+*     This file implements the low level 3D graphics functions required
+*     by the rest of AST. These implementations simply report an error
+*     when called.
+
+*  Inheritance:
+*     This module is not a class and does not inherit.
