def initialize #:nodoc:
  super('batch', takes_commands: false)
  short_desc("Execute a single command on multiple files")
  long_desc(<<~EOF)
    This command allows executing a single command for multiple input files, thereby reducing
    the overall execution time.

    The first argument is used as a hexapdf command line (but without the binary name) and
    the rest as input files. The specified command will be executed for each input file, with
    {} being replaced by the file name.
  EOF
