--  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.
