Comment:

 One gets sparse files by creating the datasets in the index file with the
 same extents as in the "heavy" data files but not writing any data into
 them. The one downside that the sparse files have is that the current
 hdf5_merge etc. are not smart enough to copy the sparse dataset as a
 sparse dataset, instead they would write "heavy" file with the datasets
 all filled with zeroes. Attached please find a patch that does this.
