You can use require-or-install in a batch mode using :

(require 'require-or-install)
(setq install-elisp-repository-directory "~/.emacs.d/auto/")
(add-path install-elisp-repository-directory)

(unless (file-directory-p install-elisp-repository-directory)
  (make-directory install-elisp-repository-directory))

(setq require-or-install-confirm-flag nil)
(setq install-elisp-confirm-flag nil)

But you'll have to trust the EmacsWiki or the others urls.

With no parameters require-or-install will try to get the library from
EmacsWiki. You do not want to do this every times a require fails.
