            TARGET SOURCES

This program will add histograms, trees and other objects from a list
of ROOT files and write them to a target ROOT file. The target file is
newly created and must not exist, or if -f ("force") is given, must
not be one of the source files.

OPTIONS:
  -a                                   Append to the output
  -k                                   Skip corrupt or non-existent files, do not exit
  -T                                   Do not merge Trees
  -O                                   Re-optimize basket size when merging TTree
  -v                                   Explicitly set the verbosity level: 0 request no output, 99 is the
                                       default
  -j                                   Parallelize the execution in multiple processes
  -dbg                                 Parallelize the execution in multiple processes in debug mode (Does
                                       not delete partial files stored inside working directory)
  -d                                   Carry out the partial multiprocess execution in the specified
                                       directory
  -n                                   Open at most 'maxopenedfiles' at once (use 0 to request to use the
                                       system maximum)
  -cachesize                           Resize the prefetching cache use to speed up I/O operations(use 0 to
                                       disable)
  -experimental-io-features            Used with an argument provided, enables the corresponding experimental
                                       feature for output trees
  -f                                   Force overwriting of output file.
  -f[0-9]                              Gives the ability to specify the compression level of the target file
                                       (by default 4)
  -fk                                  Sets the target file to contain the baskets with the same compression
                                       as the input files (unless -O is specified). Compresses the meta data
                                       using the compression level specified in the first input or the
                                       compression setting after fk (for example 206 when using -fk206)
  -ff                                  The compression level use is the one specified in the first input
  -f0                                  Do not compress the target file
  -f6                                  Use compression level 6 (see TFile::SetCompressionSettings for the
                                       supported range of values)
  TARGET                               Target file
  SOURCES                              Source files

If TARGET and SOURCES have different compression settings a slower
method is used. For options that takes a size as argument, a decimal
number of bytes is expected. If the number ends with a ``k'', ``m'',
``g'', etc., the number is multiplied by 1000 (1K), 1000000 (1MB),
1000000000 (1G), etc. If this prefix is followed by i, the number is
multiplied by the traditional 1024 (1KiB), 1048576 (1MiB), 1073741824
(1GiB), etc. The prefix can be optionally followed by B whose casing
is ignored, eg. 1k, 1K, 1Kb and 1KB are the same.
