+--  This package contains the function used to read SPARK cross-reference
+--  information from an ALI file and populate the tables defined in package
+--  SPARK_Xrefs with the result.
+
+generic

+   --  providing access to the ALI file is the callers' responsibility.
+
+   with function Getc return Character is <>;
+   --  Get next character, positioning the ALI file ready to read the following
+   --  character (equivalent to calling Nextc, then Skipc). If the end of file
+   --  is encountered, the value Types.EOF is returned.
+
+   with function Nextc return Character is <>;
+   --  Look at the next character, and return it, leaving the position of the
+   --  file unchanged, so that a subsequent call to Getc or Nextc will return
+   --  this same character. If the file is positioned at the end of file, then
+   --  Types.EOF is returned.
+
+   with procedure Skipc is <>;
+   --  Skip past the current character (which typically was read with Nextc),
+   --  and position to the next character, which will be returned by the next
+   --  call to Getc or Nextc.
+
+procedure Get_SPARK_Xrefs;
+--  Load SPARK cross-reference information from ALI file text format into
+--  internal SPARK tables (SPARK_Xrefs.SPARK_Xref_Table,
+--  SPARK_Xrefs.SPARK_Scope_Table and SPARK_Xrefs.SPARK_File_Table). On entry
+--  the input file is positioned to the initial 'F' of the first SPARK specific
+--  line in the ALI file. On return, the file is positioned either to the end
+--  of file, or to the first character of the line following the SPARK specific
+--  information (which will never start with an 'F').
+--
+--  If a format error is detected in the input, then an exception is raised
+--  (Ada.IO_Exceptions.Data_Error), with the file positioned to the error.
