If the dimension, variable, and attribute names in the HDF file conform
to netCDF specifications (e.g., no special characters such as *), then
it should work.

Large HDF files may cause problems because the dump step creates an
ASCII representation of the data in the file.

Finally, it's not all that difficult to work with HDF4 files in IDL,
particularly the 'Scientific Data Set' variant. However with HDF5, all
bets are off.
