[Zope] CookieCrumbler login_form examples?

Does anybody have an example of login_form and logged_out documents that will operate without CMF? I'm putting together a site where we don't need all of the content-management facilities of CMF, but would really like to use a cookie-based authentication method like the one that CookieCrumbler uses. If anybody has another suggestion, I'd certainly like to hear it. --- Chris
