I imagine that by now a whole bunch of people have come up with ways
to back things up or synchronize trees.  I've used mkfs(8) a lot, then
clone(1), etc., but I really wanted to also be able to remove files no
longer present (while not touching any mtimes for up-to-date stuff,
etc.).  After a bunch of iterations of scripts with diff(1) and
others, I now use derp(1) together with the equivalent of dircp(1) and
some awk [1].  This prints two commands, one to remove files, the
other to unpack new or modified ones.  Of course, it's slow and has
tar(1)'s filename length limit, but I kind of like it.  I'm very
interested in hearing about other solutions though :)

Cheers and thanks for the post,
