Command Argument Example
========================

   Here is an example of using Emacs with arguments and options.  It
assumes you have a Lisp program file called `hack-c.el' which, when
loaded, performs some useful operation on the current buffer, expected
to be a C program.

     emacs -batch foo.c -l hack-c -f save-buffer >& log

This says to visit `foo.c', load `hack-c.el' (which makes changes in
the visited file), save `foo.c' (note that `save-buffer' is the
function that `C-x C-s' is bound to), and then exit back to the shell
(because of `-batch').  `-batch' also guarantees there will be no
problem redirecting output to `log', because Emacs will not assume that
it has a display terminal to work with.
