EPILOG = """Examples:
- rootmv source.root:hist* dest.root
  Move all histograms whose named starts with 'hist' from 'source.root' to 'dest.root'.
 
- rootmv source1.root:hist1 source2.root:hist2 dest.root
  Move histograms 'hist1' from 'source1.root' and 'hist2' from 'source2.root' to 'dest.root'.
 
- rootmv --recreate source.root:hist dest.root
  Recreate the destination file 'dest.root' and move the histogram named 'hist' from 'source.root' into it.
 
- rootmv -c 101 source.root:hist dest.root
  Change the compression settings of the destination file 'dest.root' to ZLIB algorithm with compression level 1 and move the histogram named 'hist' from 'source.root' into it.
  Meaning of the '-c' argument is given by 'compress = 100 * algorithm + level'.
  Other examples of usage:
    * -c 509 : ZSTD with compression level 9
    * -c 404 : LZ4 with compression level 4
    * -c 207 : LZMA with compression level 7
