+If nc-config is found in the default path or in the <path to install tree>/bin directory, then optional support of netcdf-4 will be tested.

 The newer NetCDF-4 library offers features such as per-variable compression (using the deflate algorithm) and chunking which require the HDF5 library. To enable this, "--enable-netcdf4" (and perhaps --with-hdf5=<path_to_hdf5>) must be added to netcdf configure. 
 
-GDAL 1.9 includes support for NetCDF-4 file format, as well as the 64-bit offset file format.  HDF4 and HDF5 files are also supported, although the respective driver is used if available.  The syntax "NETCDF:<file>" forces the use of the NetCDF driver.
