Exactly!

This lets the shell interpret the Emacs script source.

The following prints nothing here for me:

  #!/bin/sh

  emacs -Q -batch -l /dev/stdin <<EOF
  (let ((var-list (list 'foo$HOME 'bar$LOGNAME)))
    (dolist (var var-list)
      (message "Hello %s" var)))
  EOF

I ended up writing a short shell wrapper, called `emacs-script', like
the following:

    #!/bin/sh
    exec emacs -Q -batch -l "$@"

This lets me write scripts in Elisp by using:

  #!/usr/bin/env emacs-script

  (let ((var-list (list 'foo$HOME 'bar$LOGNAME)))
    (dolist (var var-list)
      (message "Hello %s" var)))

which correctly prints:

  $ ./hw.el
  Hello foo$HOME
  Hello bar$LOGNAME
  $
