David,

Thanks for your guidance.  I'm not sure exactly what to add to the 
request tracker at this time.   Once I play with your suggestions and 
the library a little more maybe I will know.

FYI - I/We have already wrapped the FLTK gui with SWIG and it 
works OK.   Then I learned about the BPL and subclassing C++ 
classes within Python is pretty darn amazing.  Your function 
overloading is much cleaner too.  So, I'm prototyping a wrapper 
with BPL to see what it's like.   

I don't have the link right here, but long term I'm going to look into 
generating the wrapper from gcc-xml output.  GCC-xml is a 
modified version of gcc that spits out an XML representation of the 
C++ program.   Wouldn't that be something?
