[Zope] Product module reloading

First off, Zope is amazing. It is a wonderful environment to work in. I am new to Python, Web Applications and Zope, but researching the other options (php3, Java, etc) I am glad to have found Zope. I have spent a bit of time surveying what is needed for my project and I have chosen to write a python product. Now I am in the edit-debug stage. Is there a streamlined way to reload my product module, and the products imported modules without restarting the ZServer? I have tried exporting a "reload_mod": reload(module) method in my product's __init__.py but Zope complains that it can't find the reload_mod method (http://localhost:8080/reload_mod). Thanks, Sean
