I suspect you'll want to use one of the commands that allows you to get 
the results of a system call. Without the Python docs in front of me, I 
think that's 'os.popen' or similar. Maye you can do it with 'os.system', 
but I don't do it enough to have memorized it.

Split the results from stdin into elements of a list(by newline, 
probably), and call it with a list iterator (like dtml-in) to do your 
rendering. Shouldn't be more that five or six lines.
