-- This package contains the search functions from Ada.Strings.Fixed. They
-- are separated out because they are shared by Ada.Strings.Bounded and
-- Ada.Strings.Unbounded, and we don't want to drag other irrelevant stuff
40 -- from Ada.Strings.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.
