Ward and netCDF team,
Thanks for all the enhancements, debug, and refactoring that went into this
release. I know there was a lot.
My group is interested in the new per-variable chunk sizing for nccopy. It
seems that per-variable chunk sizing is missing from the RC2 documentation
for nccopy (User's Guide under NetCDF Utilities). Can you please add
this? Confession, I did not have a chance to build and check the man page
yet. Thanks.
