I don't know what legends you've heard of, but I suspect that this is
not it.  (It's something I hack about a year ago, and nobody knew
about it until pretty recently.)  I suspect that to be completely
serious about it, you'd implement my thing inside Emacs, wire that to
some interactive `find-multiple-files', and in the resulting buffer
rebind the `save-buffer' command to do the unpacking thing.
