DESCRIPTION
Convert a generic NetCDF file into a PyTables (HDF5 format) file

A summary of options is included below.
-h Prints a help text.
-v Show more information.
-o Overwite destination file.
--complevel=(0-9)
Sets a compression level (0 for no compression, which is the

Sets the compression library to be used during the copy. lib can
be set to "zlib", "lzo" or "ucl". Defaults to "zlib".
--shuffle=(0|1)
Activate or not the shuffling filter (default is active if
complevel>0).
--fletcher32=(0|1)
Whether activate or not the fletcher32 filter (not active by
default).
--unpackshort=(0|1)
Unpack short integer variables to float variables using
scale_factor and add_offset netCDF variable attributes (not
active by default).
--quantize=(0|1)
Quantize data to improve compression using
least_significant_digit netCDF variable attribute (not active by
default). See
http://www.cdc.noaa.gov/cdc/conventions/cdc_netcdf_standard.shtml
