> As with many programs, you can use the argument '--' to tell Emacs not

> $ emacs --script -- --help

> Some boiler-plate for an elisp script is:
> 
> #!/bin/sh
> ":"; exec emacs -Q --script "$0" -- "$@" # -*-emacs-lisp-*-
> (pop argv) # Remove the "--" argument
> # ...
> # Always exit explicitly. This returns the desired exit
> # status, and also avoids the need to (setq argv nil).
