33   --  Returns False right away if no source files, or if all source files

36   function Next_Main_Lib_File return File_Name_Type;
37   --  This function returns the name of the next library info file specified
38   --  on the command line. It is an error to call Next_Main_Lib_File if no
39   --  more library information files exist (i.e. Next_Main_Lib_File may be
40   --  called only if a previous call to More_Lib_Files returned True). This
41   --  name is the simple name, excluding any directory information.

62   --  file to be output (in the case of Ada, it must have an extension
