[Grok-dev] an application installation script?

The way I see it, having to add the application through a web UI is  
contrary to the idea of filesystem based development.

I would rather have the application configured by directions in  
setup.py, zope.conf or similar. That way I can store it in SVN. I  
would also like to be able to provide these settings to "grokproject"  
when I create my Grok project instance (with the option of copying an  
existing data.fs file) in order to have my project ready to run  
straight off the bat. (maybe this could be done with eggs, I haven't  
quite figured out how to use them :) )

I would also like a new command "rundevzope" that I could use during  
development (with development settings turned on), whereas  
"runzope" (through "zopectl") is for deployment. Then rundevzope  
could run the application as root if nothing else is specified.
