Re: newtCDF-Java 2.2.10

Hi Robert:

Yes, its true we are using some 1.4 stuff like the URI class. Im not sure what else, its 
been a long time since I've run 1.3. It may be that the "minimal" netcdf 
library will work ok on 1.3 though. It would need to be recompiled under 1.3. If you want 
to try that, download the soruce distribution, and just compile ucar.ma2 and ucar.nc2. I 
_think_ it will work.

Generally 1.4 is better, faster, and less buggy than 1.3, im surprised that 
iText has problems. Is there anyone developing that still?

Sorry for not documenting this, I will update the web page.
