+--  Spelling checker
+
+--  This package provides a utility generic routine for checking for bad
+--  spellings. This routine must be instantiated with an appropriate array
+--  element type, which must represent a character encoding in which the
+--  codes for ASCII characters in the range 16#20#..16#7F# have their normal
+--  expected encoding values (e.g. the Pos value 16#31# must be digit 1).

+   generic
+      type Char_Type is (<>);
+      --  See above for restrictions on what types can be used here
+
+      type String_Type is array (Positive range <>) of Char_Type;
+
+   function Is_Bad_Spelling_Of
+     (Found  : String_Type;
+      Expect : String_Type) 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 if the
+   --  character encoding represents upper/lower case.
+   --
+   --  Note: the spec of this routine is deliberately rather vague. This
+   --  routine is the one 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.
