-------------------------------------------------------------------------
* Visible changes since Unum 4.0:
-------------------------------------------------------------------------

- To support Python 2.5 and higher, the method Unum.as was renamed to
Unum.asUnit; this was necessary since "as" became a reserved word.
If you are still using old versions of Python, both names are
available.

- In addition to unit names in uppercase, unit names in the correct case
are now available. So, both "kg" and "KG" refer to the kilogram Unum,
and both "eV" and "EV" refer to the electron volt Unum.

- Value types are no longer automatically coerced to floats. This allows
the fractions.Fraction standard library type to be used, but may
introduce incompatibilities with old code from integer vs. floating
point division. In Python 3.x there is no problem.

- Prefixed versions of the 7 base SI units are supplied. So you can use
"cm", "ns", "kA", "mK", "pmol", "Mcd", and "g" out of the box.

-------------------------------------------------------------------------
* Prerequisites:
-------------------------------------------------------------------------

- Python 2.2 or higher. Python 3.x should work as well, but please
report any bugs.

-------------------------------------------------------------------------
* To install Unum:
-------------------------------------------------------------------------

- unzip Unum installation files to any directory.
- cd <install-directory>
- python setup.py install
this will install Unum packages in your Python site-packages directory
i.e. it will create the directory <python-site-packages-dir>/unum
- if the installation is successful (see below),
you can safely remove <your-install-directory>

- alternately, if you have setuptools installed you can do:
"easy_install unum" to obtain it online from PyPI.

- On Windows you may need to do "python -m easy_install unum" instead.
- On Linux you may need to do "sudo easy_install unum".

-------------------------------------------------------------------------
* To run the test cases:
-------------------------------------------------------------------------

- cd <install-directory>
- python setup.py test
