I'm not sure. Luca and I have tried it, it seems to do the same job as 
the hdf5_merge utility from CactusPUGHIO/IOHDF5; all datasets from the 
two input files are simply copied over into the output file, there is no 
recombination of different processor components into a single unchunked 
dataset. I guess that's what Luca was originally asking for.

It's also not clear yet whether we really need such a recombiner utility 
for Carpet HDF5 datafiles. The question arised when Luca et.al. wanted 
to visualise Carpet HDF5 data using Matlab. He is currently 
investigating ways of how to do that within Matlab for both unchunked 
and chunked data.
