+    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.
