[Dar-support] last slice exec option?

[Daniel J. <tek...@gm...>]

I'm trying to write a script based on dar that will backup files to
DVDs.  The trick is that mkisofs doesn't support files big enough to
fill up a DVD.  As a result of that I am trying to have dar make
slices that are a third of the size needed to fill a DVD. Then have
the script dar executes between slices determin if either there are
three full slices to burn to a DVD, or less than three, but the the
end of the archive before burning a disk.  Is there any way to get dar
to tell the script it executes that the archive file it just wrote is
the last in the set?
