Thanks Kent, that explains a lot about how things work.

I am doing this as a learning exercise, though I hadn't realized those  
are precisely TG's components. I'm actually coming at this from  
Django, and wanted to approach things at a lower level (every time a  
friend asks me to make a website for them I use it as an excuse to  
learn some new framework components). I wasn't really missing Django  
until I got to the 'CMS backend' stage of things – forms for models,  
validation, etc. I'll stick through the learning exercise, but it will  
be *very* nice to return to a full framework package...
