    longDescription = ''
      GNU ddrescue is a data recovery tool.  It copies data from one file
      or block device (hard disc, cdrom, etc) to another, trying hard to
      rescue data in case of read errors.

      The basic operation of ddrescue is fully automatic.  That is, you
      don't have to wait for an error, stop the program, read the log, run
      it in reverse mode, etc.

      If you use the logfile feature of ddrescue, the data is rescued very
      efficiently (only the needed blocks are read).  Also you can
      interrupt the rescue at any time and resume it later at the same
      point.

      Automatic merging of backups: If you have two or more damaged copies
      of a file, cdrom, etc, and run ddrescue on all of them, one at a
      time, with the same output file, you will probably obtain a complete
      and error-free file.  This is so because the probability of having
      damaged areas at the same places on different input files is very
      low.  Using the logfile, only the needed blocks are read from the
      second and successive copies.
