--  This package contains the function used to read Alfa information from the

--  internal tables defined in package Alfa, and output text information for

--  the ALI file. The interface allows control over the destination of the

--  output, so that this routine can also be used for debugging purposes.

   --  The following procedures are used to output text information. The

   --  destination of the text information is thus under control of the

   --  particular instantiation. In particular, this procedure is used to

   --  write output to the ALI file, and also for debugging output.

   with function Write_Info_Col return Positive is <>;

   --  Return the column in which the next character will be written

   with procedure Write_Info_Char (C : Character) is <>;

   --  Output one character

   with procedure Write_Info_Initiate (Key : Character) is <>;

   --  Initiate write of new line to output file, the parameter is the

   --  keyword character for the line.

   with procedure Write_Info_Nat (N : Nat) is <>;

   --  Write image of N to output file with no leading or trailing blanks

   with procedure Write_Info_Terminate is <>;

   --  Terminate current info line and output lines built in Info_Buffer

procedure Put_Alfa;

--  Read information from Alfa tables (Alfa.Alfa_Xref_Table,

--  Alfa.Alfa_Scope_Table and Alfa.Alfa_File_Table) and output corresponding

--  information in ALI format using the Write_Info procedures.
