[Paraview] netCDF grids and Paraview 3.3.0

[John Biddiscombe]

I replied off list, but in case anyone on list is looking for a netCDF 
reader for paraview

http://www.cscs.ch/index.php?option=com_content&task=view&id=96&Itemid=132

it's state is currently a bit flaky as I have not updated it in a while, 
but some users inform me it is still working fine for them.
