-- Abstract     :  
--   This package provides useful parent types for derived
--   dimensional units. That is, it makes it possible to
--   do this:
--      type Feet is new Integer_Unit;
--      type Radians is new Float_Unit;
--   Objects of type Feet can be added together, but can't be
--   multiplied together to get a result in feet.
--
--  See Dr. Dobb's Journal of Software Tools issue #127
--  (May 1987) page 50 for a complete description of how to
--  use this package.
--
--  Unfortunately Dr. Dobb failed to publish the package body and
--  the test routines.
--
--  The complete set of files consists of:
--    DUNITS.ADA (DIMENSIONAL_UNITS package specification)
--    DUNITB.ADA (DIMENSIONAL_UNITS package body)
--    DUEX.ADA   (procedure Speed_Gun example program)
--    DUTEST.ADA (Exhaustive test program with 3 subunits)
--    DUTEST1.ADA (subunit 1)
--    DUTEST2.ADA (subunit 2)
--    DUTEST3.ADA (subunit 3)
