Right... makes sense.  I certainly considered the C++ port option.  I'll 
have to look a bit closer at the StringTemplate code and see what I'd be 
getting myself into :-)

This seems like a not-too bad tradeoff, especially in the short term.  I 
have done some research, and am thinking of Python together with 
Boost.Python.  I will likely go this route and investigate a C++ port 
for a better long-term solution.
