+*  Name:
+*     normmap.h
+
+*  Type:
+*     C include file.
+
+*  Purpose:
+*     Define the interface to the NormMap class.
+
+*  Invocation:
+*     #include "normmap.h"
+
+*  Description:
+*     This include file defines the interface to the NormMap class and
+*     provides the type definitions, function prototypes and macros,
+*     etc.  needed to use this class.
+*
+*     The NormMap class implements Mappings which use a Frame to
+*     normalise the input axis values.
+
+*  Inheritance:
+*     The NormMap class inherits from the Mapping class.
