       A summary of options is included below.

       -o     Overwite destination file.

       -R RANGE
	      Select a RANGE of rows in the form start,stop,step during the copy of all the leaves.

       --non-recursive
	      Do not do a recursive copy. Default is to do it.

       --dest-title=title
	      Title for the new file (if not specified, the source is copied).

       --dont-copy-userattrs
	      Do not copy the user attrs (default is to do it).

       --overwrite-nodes
	      Overwrite destination nodes if they exist. Default is not to overwrite them.

       --complevel=(0-9)
	      Set a compression level (0 for no compression, which is the default).

       --complib=lib
	      Set the compression library to be used during the copy. lib can be set to "zlib", "lzo", "ucl" or "bzip2". Defaults to "zlib".

       --shuffle=(0|1)

       --dont-regenerate-old-indexes
	      Disable regenerating old indexes. The default is to regenerate old indexes as they are found.
