Thanks to all of you for these suggestions. Both h5ls -v and h5dump -p
provide the information about the size of the dataset, with h5ls -v
providing more detailed information (allocated size plus real usage).
Unfortunately, both produce tons of other output, requiring serious
postprocessing for extracting just the size information for a large
number of datasets in a large number of files.
