How do I create a dynamic wrapper for another language?

[Whitney Battestilli]

Has,

Thanks!  This is exactly what I was missing.  

I appreciate everybody's suggestions and the loads of general good info
on this list.  I'm going to be able to get back into python for a few
months ( after a few year break ). I'll try to lurk on the list and
pitch in.

Thanks again,
--Whitney.
