32 -- This package contains search functions from Ada.Strings.Wide_Wide_Fixed.
33 -- They are separated because Ada.Strings.Wide_Wide_Bounded shares these
34 -- search functions with Ada.Strings.Wide_Wide_Unbounded, and we don't want
35 -- to drag other irrelevant stuff from Ada.Strings.Wide_Wide_Fixed when using
36 -- the other two packages. We make this a private package, since user
37 -- programs should access these subprograms via one of the standard string
38 -- packages.
