We use both netCDF and CDF and it would be convenient to distinguish
between them using different conventional file extensions. I propose
defining a new recommended file extension for netCDF. I suggest ".nc".
ncgen appends the ".cdf" extension if "-o outputfile" is not specified.
This appears to be the only place where ".cdf" is built into the
standard netCDF software. I suggest a new flag (say -N) similar to -n,
except that it would generate the new default file extension. Note that
-n would be retained for compatibility and would still produce ".cdf".
It would be necessary to modify the "NetCDF User's Guide". I suggest it
should mention both the new recommended extension & the old obsolete
".cdf".
