-#if !defined( SLAMAP_INCLUDED ) /* Include this file only once */
-#define SLAMAP_INCLUDED
-/*
-*+
-* Name:
-* slamap.h
-
-* Type:
-* C include file.
-
-* Purpose:
-* Define the interface to the SlaMap class.
-
-* Invocation:
-* #include "slamap.h"
-
-* Description:
-* This include file defines the interface to the SlaMap class and
-* provides the type definitions, function prototypes and macros,
-* etc. needed to use this class.
-*
-* The SlaMap class encapsulates the conversions provided by the
-* SLALIB library (SUN/67) for converting between different sky
-* coordinate systems. Since, typically, a sequence of these
-* SLALIB conversions is required, an SlaMap can be used to
-* accumulate a series of conversions which it then applies in
-* sequence.
-
-* Inheritance:
-* The SlaMap class inherits from the Mapping class.
-
-* Attributes Over-Ridden:
-* None.
-
-* New Attributes Defined:
-* None.
-
-* Methods Over-Ridden:
-* Public:
-* astTransform
-* Use an SlaMap to transform a set of points.
-
-* Protected:
-* astMapMerge
-* Simplify a sequence of Mappings containing an SlaMap.
-
-* New Methods Defined:
-* Public:
-* astSlaAdd
-* Add a coordinate conversion step to an SlaMap.
-
-* Private:
-* None.
-
-* Other Class Functions:
-* Public:
-* astIsASlaMap
-* Test class membership.
-* astSlaMap
-* Create an SlaMap.
-
-* Protected:
-* astCheckSlaMap
-* Validate class membership.
-* astInitSlaMap
-* Initialise an SlaMap.
-* astLoadSlaMap
-* Load an SlaMap.
-
-* Macros:
-* None.
-
-* Type Definitions:
-* Public:
-* AstSlaMap
-* SlaMap object type.
-
-* Protected:
-* AstSlaMapVtab
-* SlaMap 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.

-
-* History:
-* 26-APR-1996 (RFWS):
-* Original version.
-* 26-SEP-1996 (RFWS):
-* Added external interface and I/O facilities.
-* 23-MAY-1997 (RFWS):
-* Over-ride the astMapMerge method.
-* 15-OCT-2002 (DSB):
-* Added astSTPConv, astSTPConv1, and STP coordinate system macros.
-* 8-JAN-2003 (DSB):
-* Added protected astInitSlaMapVtab method.
-* 22-FEB-2006 (DSB):
-* Added cvtextra to the AstSlaMap structure.
