Er, I suppose -- if you are acquainted with that particular shell
variable syntax (I suspect knowledge of sed is far more widespread).
[personally, I know that syntax has something to do with replacing
something with something else, but really haven't much clue other than
that, and I always _thought_ it was bash-specific and so avoided using
any of that stuff.]
