(To all Gurus: Please correct me, if I'm wrong)

@@ marks a given path component explicitely as a view of the previous object.

Example:

http://zopeserver/contents.html 

Could mean either "The object named 'contents.html' in the root folder" or
(if there is no such object) "The 'contents.html' view (List of contained
objects) of the root folder" - the object is preferred.

http://zopeserver/@@contents.html

Will always display the list of contained objects of the root folder - no matter
if there's a object 'contents.html' or not.

I'm maintaining a wiki which tries to answer all those little questions around
zope3. It's in german (Sorry, my employer depends on it):
