--  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 necessary 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.
