Note: If an object has been written to a file multiple times, rootcp will copy only the latest version of that object.

Examples:
- rootcp source.root dest.root
  Copy the latest version of each object in 'source.root' to 'dest.root'.

- rootcp source.root:hist* dest.root
  Copy all histograms whose names start with 'hist' from 'source.root' to 'dest.root'.

- rootcp source1.root:hist1 source2.root:hist2 dest.root
  Copy histograms 'hist1' from 'source1.root' and 'hist2' from 'source2.root' to 'dest.root'.

- rootcp --recreate source.root:hist dest.root
  Recreate 'dest.root' and copy the histogram named 'hist' from 'source.root' into it.

- rootcp -c 1 source.root:hist dest.root
  Change compression factor of 'dest.root' if not existing and copy the histogram named 'hist' from 'source.root' into it.
