unified archive scripts -- snarfer is the packer side

[Fred T. Hamster]

we just need a universal snarf:

snarf filenameblah things to snarf lots maybe

where it will make a snarf file called filenameblah.snarf
and fill it with the goods from the things to snarf.

this could be an issue with our exclusions; we would not be able to use this
as a really general tool, since it will leave out exes etc.
=>
need a flag --sourcey
to mean the current behavior.
no flag will pack everything.
that would fix it.

actually, snarf is a bit specific, isn't it?
it uses some extra files added to the archive for tracking some
things...
actually that's a pretty cool approach.
maybe we should develop it in that direction *more*
so that it can be generalized zipper++ kinda thing.
