Nope.

There aren't, but it'd be cool if someone could write one down.


Basically, by importing zc.sourcefactory in your code, you introduce  
a *dependency*. Dependencies are managed in setup.py. So edit  
setup.py and add 'zc.sourcefactory' to the install_requires list.  
Then run bin/buildout again. It will download and install  
zc.sourcefactory now.

This is, by the way, how all of the Zope packages are installed  
automatically. Your package depends on 'grok' and 'grok' depends on  
various 'zope.*' packages. buildout simply makes sure that all the  
dependencies are installed.
