* Comments:
*
* Modifications:
* July 2004: Introduced the extra EC or NN option for SZIP
* October 2006: Added a new switch -n, that allows to write the dataset
* using a native type. The default to write is the file type.
*
* Modification:
* Peter Cao, June 13, 2007
* Add "-L, --latest" option to pack a file with the latest file format
* PVN, November 19, 2007
* adopted the syntax h5repack [OPTIONS] file1 file2
* PVN, November 28, 2007
* added support for multiple global filters
* PVN, May 16, 2008
* added backward compatibility for -i infile -o outfile
* PVN, August 20, 2008
* add a user block to repacked file (switches -u -b)
* PVN, August 28, 2008
* add options to set alignment (H5Pset_alignment) (switches -t -a)
