  32 --  Spelling checker
  33
  34 --  This package provides a utility routine for checking for bad spellings
  35 --  for the case of Wide_String arguments.
  36
  37 package GNAT.Wide_Spelling_Checker is
  38    pragma Pure;
  39
  40    function Is_Bad_Spelling_Of
  41      (Found  : Wide_String;
  42       Expect : Wide_String) return Boolean;
  43    --  Determines if the string Found is a plausible misspelling of the string
  44    --  Expect. Returns True for an exact match or a probably misspelling, False
  45    --  if no near match is detected. This routine is case sensitive, so the
  46    --  caller should fold both strings to get a case insensitive match.
  47    --
  48    --  Note: the spec of this routine is deliberately rather vague. It is used
  49    --  by GNAT itself to detect misspelled keywords and identifiers, and is
  50    --  heuristically adjusted to be appropriate to this usage. It will work
  51    --  well in any similar case of named entities.
