e-mail addresses from the pkg-descr file that could reasonably be mistaken for maintainer contact information in order to avoid confusion on the part of users looking for support. As a pleasant side effect this also avoids confusion and/or frustration for people who are no longer maintaining those ports.

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. 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 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.
