how to make emacs lisp take argv from shell command line?

[Xah Lee]

i'm writing a text processing emacs lisp script. To be run like this:

emacs --script process_log.el filepath

how to make the script take the argument? i.e. that filepath?

e.g. in perl, python, it's typically argv[1] etc.

Thanks.

Can you give a small example of what the script file would look like ?
Is it a lambda or a progn for the main program ?

command-line-args's value is
("emacs" "lisp.el")
Documentation:
Args passed by shell to Emacs, as a list of strings.

one recent example is:
