+--  Spelling checker
+
+--  This package provides a utility routine for checking for bad spellings
+--  for the case of Wide_String arguments.
+
+package GNAT.Wide_Spelling_Checker is
+   pragma Pure;
+
+   function Is_Bad_Spelling_Of
+     (Found  : Wide_String;
+      Expect : Wide_String) return Boolean;
+   --  Determines if the string Found is a plausible misspelling of the string
+   --  Expect. Returns True for an exact match or a probably misspelling, False
+   --  if no near match is detected. This routine is case sensitive, so the
+   --  caller should fold both strings to get a case insensitive match.
+   --
+   --  Note: the spec of this routine is deliberately rather vague. It is used
+   --  by GNAT itself to detect misspelled keywords and identifiers, and is
+   --  heuristically adjusted to be appropriate to this usage. It will work
+   --  well in any similar case of named entities.
