+*  Name:
+*     ratemap.h
+
+*  Type:
+*     C include file.
+
+*  Purpose:
+*     Define the interface to the RateMap class.
+
+*  Invocation:
+*     #include "ratemap.h"
+
+*  Description:
+*     This include file defines the interface to the RateMap class and
+*     provides the type definitions, function prototypes and macros,
+*     etc. needed to use this class.
+
+*  Inheritance:
+*     The RateMap class inherits from the Mapping class.
+
+*  Attributes Over-Ridden:
+*     None.
+
+*  New Attributes Defined:
+*     None.
+
+*  Methods Over-Ridden:
+*     Public:
+*        None.
+*
+*     Protected:
+*        astMapMerge
+*           Merge a RateMap within a sequence of Mappings.
+*        astTransform
+*           Transform a set of points.
+
+*  New Methods Defined:
+*     Public:
+*        None.
+*
+*     Protected:
+*        None.
+
+*  Other Class Functions:
+*     Public:
+*        astIsARateMap
+*           Test class membership.
+*        astRateMap
+*           Create a RateMap.
+*
+*     Protected:
+*        astCheckRateMap
+*           Validate class membership.
+*        astInitRateMap
+*           Initialise a RateMap.
+*        astInitRateMapVtab
+*           Initialise the virtual function table for the RateMap class.
+*        astLoadRateMap
+*           Load a RateMap.
+
+*  Macros:
+*     None.
+
+*  Type Definitions:
+*     Public:
+*        AstRateMap
+*           RateMap object type.
+*
+*     Protected:
+*        AstRateMapVtab
+*           RateMap virtual function table type.
+
+*  Feature Test Macros:
+*     astCLASS
+*        If the astCLASS macro is undefined, only public symbols are
+*        made available, otherwise protected symbols (for use in other
+*        class implementations) are defined. This macro also affects
+*        the reporting of error context information, which is only
+*        provided for external calls to the AST library.
