Copy any Leaf, Group or complete subtree from a PyTables file into another file.
A summary of options is included below.
-h

-v

-RRANGE
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)
Activate or not the shuffling filter (default is active if complevel>0).
--fletcher32=(0|1)
Whether to activate or not the fletcher32 filter (not active by default).
--keep-source-filters
Use the original filters in source files. The default is not doing that if any of --complevel, --complib, --shuffle or --fletcher32 option is specified.
--upgrade-flavors
When repacking PyTables 1.x files, the flavor of leaves will be unset. With this, such a leaves will be serialized as objects with the internal flavor ("numpy" for 2.x series).
--dont-regenerate-old-indexes
Disable regenerating old indexes. The default is to regenerate old indexes as they are found.
These utilities are documented fully by PyTables user's manual.
