-- This package defines a datatype which is most efficient for performing
-- logical operations on large arrays. See System.Generic_Vector_Operations.
-- In the future this package may also define operations such as element-wise
-- addition, subtraction, multiplication, minimum and maximum of vector-sized
-- packed arrays of Unsigned_8, Unsigned_16 and Unsigned_32 values. These
-- operations could be implemented as system intrinsics on platforms with
-- direct processor support for them.
