On behalf of the netCDF user community, thanks very much for these
developments and for the information about them!  The packages look
very useful.

I have drafted entries for each of these in the "Software for
Manipulating or Displaying NetCDF Data" web page under "Freely
Available Software":

  http://www.unidata.ucar.edu/packages/netcdf/software.html#ANDX
  http://www.unidata.ucar.edu/packages/netcdf/software.html#ANTS
  http://www.unidata.ucar.edu/packages/netcdf/software.html#NCMEX

Please look these over and let me know if the minor changes I've made
are OK, or if you want any changes.  In particular, I combined ANDX
and ANAX in one entry and I also included a link to your "ARM-tested
netCDF data tools" document at the top of the software page, since I
think it deserves some prominence.

I'd also like to include a note about these new packages in the
"What's new with netCDF" page at 

  http://www.unidata.ucar.edu/packages/netcdf/whatsnew.html

and recommend that you also send a note to the netcdfgroup mailing
list about these packages.  If you would rather have me send a posting
to the mailing list, I'll draft something up and pass it by you first.

If you'd like your names added to the entries rather than the "ARM
Program", I'd be happy to do that, but I would need more information
to get the credit right.  I've also added Sherman J. Beus and Connor
J. Flynn to the list of names we credit for helping make netCDF more
useful:

Thanks again for all your work!

--Russ
