+*  Name:
+*     fselectormap.c
+
+*  Purpose:
+*     Define a FORTRAN 77 interface to the AST SelectorMap class.
+
+*  Type of Module:
+*     C source file.
+
+*  Description:
+*     This file defines FORTRAN 77-callable C functions which provide
+*     a public FORTRAN 77 interface to the SelectorMap class.
+
+*  Routines Defined:
+*     AST_ISASELECTORMAP
+*     AST_SELECTORMAP
