HDF isn't good about deleting or renaming things. The best you can do is
create a new file by copying all the parts of the old file that you want
to keep, while dropping or renaming the parts you want to drop or
rename. Very annoying. HDF provides routines for deleting or renaming
Vgroups, but not for anything else. HDF_DELDD doesn't actually delete an
object from an HDF file, it just removes it from the list of data
descriptors. The deleted object still takes up space (which can be
released by using the hdfpack routine).
