+
+--  This child package contains a routine to read and process Source_File_Name
+--  pragmas from the gnat.adc file in the current directory. In order to use
+--  the routines in package Fname.UF, it is required that Source_File_Name
+--  pragmas be processed. There are two places where such processing takes
+--  place:
+
+--    The compiler front end (par-prag.adb), which is the general circuit
+--    for processing all pragmas, including Source_File_Name.
+
+--    The stand alone routine in this unit, which is convenient to use
+--    from tools that do not want to include the compiler front end.
+
+--  Note that this unit does depend on several of the compiler front-end
+--  sources, including osint. If it is necesary to scan source file name
+--  pragmas with less dependence on such sources, look at unit SFN_Scan.
+
+package Fname.SF is
+
+   procedure Read_Source_File_Name_Pragmas;
+   --  This procedure is called to read the gnat.adc file and process any
+   --  Source_File_Name pragmas contained in this file. All other pragmas
+   --  are ignored. The result is appropriate calls to routines in the
+   --  package Fname.UF to register the pragmas so that subsequent calls
+   --  to Get_File_Name work correctly.
+   --
+   --  Note: The caller must have made an appropriate call to the
+   --  Osint.Initialize routine to initialize Osint before calling
+   --  this procedure.
+   --
+   --  If a syntax error is detected while scanning the gnat.adc file,
+   --  then the exception SFN_Scan.Syntax_Error_In_GNAT_ADC is raised
+   --  and SFN_Scan.Cursor contains the approximate index relative to
+   --  the start of the gnat.adc file of the error.
