dar_cp - 'cp' clone command that is able to copy data located after an I/O error
dar_cp <source file> <destination file>
is similar to the standard 'cp' command, except it does not stop
copying when an I/O error is met. Instead, it skips a bit further and
continues to copy the rest of the file, as much as possible, filling the gaps
by zeroed bytes.
only accepts full filename (not directory) as argument. The reason
of its existence in dar package is that you need it if you use Parchive with
dar and have a corruption on a CD-R or any other read-only medium. You need to
copy the corrupted slice on a read-write filesystem, for Parchive be able to
repair it using slice associated redundancy files.

exists with the following codes:
- upon normal execution (be some corrupted parted skipped or not)
- syntax error on command-line
- could not open source or destination files
- any other system error met during the copy
- when some data could not be copied due to I/O error
Any signal sent to dar_cp will abort the program immediately, there is no way to
have a proper termination before the end of the process
