Physics/Unit version 0.02
=========================

This tarball includes four modules:
  Physics::Unit
  Physics::Unit::Scalar
  Physics::Unit::ScalarSubtypes
  Physics::Unit::Vector

Objects of class Physics::Unit define units of measurement that correspond
to physical quantities.  This module allows you to manipulate these units,
generate new derived units from other units, and convert from one unit
to another.  Each unit is defined by a conversion factor and a
dimensionality vector.

Objects of type Physics::Scalar store physical quantities.  Each instance
of a class that derives from Physics::Scalar holds the value of some type
of measurable quantity.  When you use this module, several new classes are
immediately available.  See the Derived Classes section of the
documentation for a complete list

The module Physics::Unit::ScalarSubtypes defines several classes that
derive from Physics::Unit::Scalar, each corresponding to a different
physical quantity.

Objects of class Physics::Unit::Vector hold vector quantities.  This
module is still in an embryonic stage.
