+*  Name:
+*     pg3d.h
+
+*  Type:
+*     C include file.
+
+*  Purpose:
+*     Define the interface to the pg3d module
+
+*  Invocation:
+*     #include "pg3d.h"
+
+*  Description:
+*     This include file defines the interface to the pg3d module
+*     (implemented in file grf3d_pgplot.c) and provides the type
+*     definitions, function prototypes and macros, etc. needed to
+*     use this module.
+*
+*     The functions in the pg3d interface provide control of the view
+*     of the 3D world coordinate system visible on the 2D PGPLOT
+*     viewport. They are provided for users of the PGPLOT implementation
+*     of the grf3D interface distributed with AST. No calls to these
+*     functions are made from within AST itself.
