Hi, Philippe Poilbarbe and Antonio S. Cofiño have generously made available their useful extensions to the nccopy utility that provide compression and other capabilities not available in the original code. I'd first like to say "Thanks!" for these useful utilities. We would like to add these capabilities in an upcoming release. We're also considering the addition of re-chunking functionality similar to what's provided by the HDF5 h5repack utility, if h5repack (in case h5repack is not already adequate for this purpose). One of the intended purposes of nccopy was to serve as an example of a generic netCDF-4 program, with the ability to read and process any valid netCDF file. It's great to see other developers taking advantage of this, to provide new useful generic utilities. --Russ
