+/*
+*  Name:
+*     grf_5.6.c
+
+*  Purpose:
+*     Implement the grf module required by AST V5.6 if no graphics system
+*     is available.
+
+*  Description:
+*     This file implements the low level graphics functions required
+*     by the rest of AST V5.6, except for those already defined in
+*     earlier grf_xxx.c files (i.e. those needed by ealier versions
+*     of AST). These implementations simply report an error when called.
+
+*  Inheritance:
+*     This module is not a class and does not inherit.
