[Zope] zope, swig and external files

Hi, Is someone able to send me an example using external methods and files generated with swig. In fact, I have a C++ program, and I want to do the interface with Zope. So I used Swig to generate the file to make me able to use Python scripts with my C++ application. But now I can't make it run on Zope! I use an external method to put my main.py, but I don't know what to do with the xx-wrap.c, xx.py, xx.i, ... files used by swig Shall I put them in Zope? and If yes shall I put them in an external Method or in an other zope object?... Can someone help me? Thanks
