+*+
+*  Name:
+*     cmpmap.h
+
+*  Type:
+*     C include file.
+
+*  Purpose:
+*     Define the interface to the CmpMap class.
+
+*  Invocation:
+*     #include "cmpmap.h"
+
+*  Description:
+*     This include file defines the interface to the CmpMap class and
+*     provides the type definitions, function prototypes and macros,
+*     etc. needed to use this class.
+*
+*     A CmpMap is a compound Mapping which allows two component
+*     Mappings (of any class) to be connected together to form a more
+*     complex Mapping. This connection may either be "in series"
+*     (where the first Mapping is used to transform the coordinates of
+*     each point and the second mapping is then applied to the
+*     result), or "in parallel" (where one Mapping transforms the
+*     earlier coordinates for each point and the second Mapping
+*     simultaneously transforms the later coordinates).
+*
+*     Since a CmpMap is itself a Mapping, it can be used as a
+*     component in forming further CmpMaps. Mappings of arbitrary
+*     complexity may be built from simple individual Mappings in this
+*     way.
+
+*  Inheritance:
+*     The CmpMap class inherits from the Mapping class.
+
+*  Attributes Over-Ridden:
+*     None.
+
+*  New Attributes Defined:
+*     None.
+
+*  Methods Over-Ridden:
+*     Public:
+*        astSimplify
+*           Simplify a CmpMap.
+*
+*     Protected:
+*        astMapList
+*           Decompose a CmpMap into a sequence of simpler Mappings.
+*        astTransform
+*           Transform a set of points.
+
+*  New Methods Defined:
+*     Public:
+*        None.
+*
+*     Protected:
+*        None.
+
+*  Other Class Functions:
+*     Public:
+*        astIsACmpMap
+*           Test class membership.
+*        astCmpMap
+*           Create a CmpMap.
+*
+*     Protected:
+*        astCheckCmpMap
+*           Validate class membership.
+*        astInitCmpMap
+*           Initialise a CmpMap.
+*        astInitCmpMapVtab
+*           Initialise the virtual function table for the CmpMap class.
+*        astLoadCmpMap
+*           Load a CmpMap.
+
+*  Macros:
+*     None.
+
+*  Type Definitions:
+*     Public:
+*        AstCmpMap
+*           CmpMap object type.
+*
+*     Protected:
+*        AstCmpMapVtab
+*           CmpMap 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.
