Readme about the verify tool
============================

The verify tool was built with HDF4.2r4 (using the --disable-netcdf
configuration option), HDF5 1.8.2, netCDF-4.0 and HDF-EOS2 (version 2.15).
It verifies the correctness of a file that has been converted from
HDF-EOS2 to netCDF-4. A user can run the command below to verify the
conversion:

  ./verify -p -v  foo.hdf foo.nc

Please note that this HDF-EOS2/netCDF-4 verifier is a beta-level convenience
tool that may give false alarms and may miss wrong conversions. False alarms
can be introduced by either a netCDF-4 library problem or excessive
strictness of the HDF-EOS2/netCDF-4 verifier.  We found one problem when we
used netCDF-4.0.0 and the problem disappeared after moving to 
netCDF-4.0.1-beta2.  The verifier traverses each HDF4 object HDF-EOS2 can
access. If some objects are invisible by the HDF-EOS2 library, those objects
are not verified.
