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. GNU ddrescue does not
truncate the output file if not asked to. So,
every time you run it on the same output file, it
tries to fill in the gaps. The basic operation of
GNU 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 GNU 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.

Changes:
This release handles SIGHUP and SIGTERM (like SIGINT) to allow clean interrupt on connection loss or system shutdown. It prints a more informative error message when reading an old log file. A note has been added to the manual about old log files.
