+/*
+*+
+*  Name:
+*     cmpregion.h
+
+*  Type:
+*     C include file.
+
+*  Purpose:
+*     Define the interface to the CmpRegion class.
+
+*  Invocation:
+*     #include "cmpregion.h"
+
+*  Description:
+*     This include file defines the interface to the CmpRegion class and
+*     provides the type definitions, function prototypes and macros,
+*     etc.  needed to use this class.
+*
+*     The CmpRegion class implement a Region which represents a simple interval
+*     on each axis of the encapsulated Frame
+
+*  Inheritance:
+*     The CmpRegion class inherits from the Region class.
+
+*  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.
