How is then Zope able to log me out of its management interface? I 
checked the frame source where the logout menu is:

<form action="/" method="POST" target="manage_main">
<span class="std-text">Logged in as <strong>admin</strong></span> 
<select class="form-element" name=":action" 
onChange="window.parent.manage_main.location.href='/'+this.options[this.selectedIndex].value">
<option value="zope_quick_start">Zope Quick Start</option>
<option value="manage_zmi_prefs">Set Preferences</option>
<option value="manage_zmi_logout">Logout</option>
</select>
<input class="form-element" type="submit" name="submit" value=" Go " />

Is there a way to use the same facility from my scripts? It seems to me 
that logging out a user is a basic operation that should be supported by 
Zope 'out of the box', without the need of additional products. Just 
wondering...
