>   Now, what I _really_ want is for 'context' to give me an object which

>   getting that with context and container, but as it turns out,
>   container, where the above python script (recursiveLinks) lives, is
>   not the container of context (the 'c' folder in this case) -- it's the
>   container of the script (near as I can tell, since the result I'm
>   getting is A: C and not A: B: C)
> 
>   How can I get 'next-folder-up' from this, in an object context so that
>   I can grab the 'title' and other attributes off of the object, and
>   recurse (as I thought I was doing above) by going to yet another
>   'next-folder-up'?

>   Any help here's appreciated.  I'm about 48 hours into learning zope. :)
