Here are some draft howto-like things some might find helpful (improvements welcome) : http://zwiki.org/ZopeDebuggingRoadmap http://zwiki.org/HowToDebugZopeInEmacs and a burning question: how can I invoke zserver such that I will get the interactive debug prompt ? I'd like to have my breakpoints trigger when I access the server in the normal way with a web browser, poke around, let it run on and do it again. I was able to do this in the past and it's useful. Many thanks! -Simon
