[Zope] dtml-var "fmt" question

[Jens Vagelpohl]

thanks for the pointer, rob. 

so it looks like i will have to write python, eh? :) my professor had 
told me that i would have to learn python in order to use Zope, and i 
told him "well... we'll see about that..."

of course i had already bought the beginners' python book by o'reilly 
a few days before that ;)
