The following packages are required:
(I have tested this with both the least current and most current versions listed)

Python 2.3 or later (Current version 2.5)
ScientificPython 2.4 or later (Current version 2.6)
Numerical Python 23.8.2
VTK 5.x (4.x versions are likely to work too)
netCDF-3

Notes:
------
Numeric Python is becoming (has become) obsolete, replaced by NumPy. However,
ScientificPython still requires it (though that may be changing).
ScientificPython provides the NetCDF reader. Hopefully, we can switch
the whole thing over to SciPy/NumPy once they add a NetCDF reader.

Once the above packages are installed, the isosurfacer should be ready to run.
If you wish to run the isosurfacer from a directory other than the one containing
the source, you will need to set your PYTHONPATH environment variable to include 
the source directory.
