Octave's -hdf5 option to the load function is only intended to be able
to load files stored with Octave's "save -hdf5" function.  It is not
designed to be a general purpose interface to HDF5.  If someone wants
to write that, it would be great, but it should probably be separate
from load/save.  It would also be nice for these functions to be
compatible with the corresponding HDF functions in Matlab, but to be
fully compatible may require implementing the newer object oriented
features first.
