netcdf

[Takeshi Enomoto]

Hi,

I decided to take over the maintenance of netcdf.

I made netcdf built without --enable-netcdf-4 by removing netcdf4 and
dap from default variants. This removes new features but made much
more compatible with many existing packages. For a few exceptions such
as nco, cdo and wgrib2, one can build netcdf and these packages with
+netcdf4.

Quote from the homepage:
Note: the netCDF-4.x releases will only build with the netCDF-4
enhanced features if "--enable-netcdf-4" is provided as a configure
option. By default the distribution will build the classic netCDF-3
library. We believe that most users will not need the enhanced
netCDF-4 features at this time.

The packages maintained by volunteers other than myself does not seem
to be modified for netcdf4.
