[Zope] Dynamic script loading

[Pawel Lewicki]

Hello,
I don't know if my question is more zopish or pythonish. I have a Zope
product. I had to add the specific functionality which is needed very
rarely. I would be glad to import external module only when it is needed, do
the job and free my mind and extra memory it consumed. How should I do that?
I have to admit that I don't find myself as an experienced Python
programmer. I just discover depths of this incredible language while
extending my Zope product.
Maybe anyone would help me with some relevant links.
Thanx in advance,

Pawel Lewicki
