+*  Name:
+*     unitnormmap.h
+
+*  Type:
+*     C include file.
+
+*  Purpose:
+*     Define the interface to the UnitNormMap class.
+
+*  Invocation:
+*     #include "unitnormmap.h"
+
+*  Description:
+*     This include file defines the interface to the UnitNormMap class and
+*     provides the type definitions, function prototypes and macros,
+*     etc.  needed to use this class.
+*
+*     A UnitNormMap is a Mapping which, in the forward direction,
+*     subtracts the specified centre and then transforms the resulting vector
+*     to a unit vector and the vector norm.
+*     The forward direction outputs one more coordinate than is input.
+*
+*     The inverse transformation of a UnitNormMap multiplies each component
+*     of the provided vector by the provided norm and adds the specified centre.
+*     The forward direction outputs one fewer coordinate than is input.
+*
+*     Example: if centre = [1, -1] then [5, 2] transforms to [4, 3] after subtracting the centre;
+*     the norm is 5, so the output is [0.8, 0.6, 5]
+*
+*     UnitNormMap is intended for applying radially symmetric distortions, as follows:
+*     - apply a UnitNormMap to produce a unit vector and norm (radius)
+*     - apply some one-dimensional mapping to the norm (radius), while passing the unit vector unchanged
+*     - apply the same UnitNormMap in the inverse direction to produce the result
+*
+
+*  Inheritance:
+*     The UnitNormMap class inherits from the Mapping class.
+
+*  Attributes Over-Ridden:
+*     None.
+
+*  New Attributes Defined:
+*     None.
+
+*  Methods Over-Ridden:
+*     Public:
+*        None.
+*
+*     Protected:
+*        ClearAttrib
+*           Clear an attribute value for a UnitNormMap.
+*        GetAttrib
+*           Get an attribute value for a UnitNormMap.
+*        SetAttrib
+*           Set an attribute value for a UnitNormMap.
+*        TestAttrib
+*           Test if an attribute value has been set for a UnitNormMap.
+*        astMapMerge
+*           Simplify a sequence of Mappings containing a UnitNormMap.
+*        astTransform
+*           Apply a UnitNormMap to transform a set of points.
+
+*  New Methods Defined:
+*     Public:
+*        None.
+*
+*     Protected:
+*        None.
+
+*  Other Class Functions:
+*     Public:
+*        astIsAUnitNormMap
+*           Test class membership.
+*        astUnitNormMap
+*           Create a UnitNormMap.
+*
+*     Protected:
+*        astCheckUnitNormMap
+*           Validate class membership.
+*        astInitUnitNormMap
+*           Initialise a UnitNormMap.
+*        astInitUnitNormMapVtab
+*           Initialise the virtual function table for the UnitNormMap class.
+*        astLoadUnitNormMap
+*           Load a UnitNormMap.
+
+*  Macros:
+*     None.
+
+*  Type Definitions:
+*     Public:
+*        AstUnitNormMap
+*           UnitNormMap object type.
+*
+*     Protected:
+*        AstUnitNormMapVtab
+*           UnitNormMap 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.
