[Zope] TAL Syntax for Iterating Over List of Dictionaries

[Dan Shafer]

Thanks, Chris, but where in the TAL do I invoke the ListAllArticlesDict 
script that generates the list of dictionaries? IOW, how do I *get* the 
articleList structure into the ZPT so I can iterate over it? That's where 
I'm stuck.
