+ (description
+ "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.")
