--  This package contains the search functions from Ada.Strings.Wide_Fixed.
--  They are separated out because they are shared by Ada.Strings.Wide_Bounded
--  and Ada.Strings.Wide_Unbounded, and we don't want to drag other irrelevant
--  stuff from Ada.Strings.Wide_Fixed when using the other two packages. We
--  make this a private package, since user programs should access these


--  subprograms via one of the standard string packages.
